feat(a11y): Globally improve accessibility for screen reader users

* feat(bwe) support setting the bandwidth from the client

Move some styles from SCSS to JSS
Remove unnecessary styles
Remove feedback stars animation option

moves e2ee verified into "Show More" section of the connection table popup.
changes the values to yes/no.

Create Tooltip component
Fix Popover positioning calculations
Add margins to popover
Remove @atlaskit/tooltip
Update all components to use the new Tooltip component

Added tooltip actions and reducers for the following functionality: when a user hovers over an element is sees the tooltip for that element and then hovers another element that has a tooltip, instead of using the delay and animations we just unmount the current tooltip and mount the next one immediately

Move region information and server count to the "More" section on both
types of tiles.

Ref: https://github.com/jitsi/lib-jitsi-meet/pull/2143

There was a fundamental change in how e2e pings work in lib-jitsi-meet where it does few pings at the beginning, pushes metrics and shuts the whole thing down, so there are no more e2ertt updates after that. Plus it's disabled by default. @paweldomas have decided with @bgrozev to remove that instead of trying to adjust. Even if e2e pings are enabled the data is not feed correctly to the indicators, what's wrong there is as soon as the pings stop going the new data does not arrive and then all you get is N/A if the UI component is recreated.

As per @fremzy, the "Save Logs" feature generates a json
file with a bevy of technical information about the
meeting. This log contains the server name, server IP
address, participant's IP addresses (only in p2p sessions)
e.t.c. While this may be a useful feature for the
admin-like 'moderator', it creates unnecessary exposure
when made readily available to all users in the meeting.

This commit fixes #8036 by a config.js option to enable
the link (disabled by default), thus giving the owner of
the deployment the choice of enabling it or not.

* feat: Adds interface config to hide lobby button.

* squash: Moves the config to config.js and add it to mobile.

* Add codec reporting to the stats window for connections.
This will report the audio/video codecs, if reported by lib-jitsi-meet.

* feat: Exposes the max enabled resolution in the connection stats popover.
* deps: lib-jitsi-meet@latest

For the most part the changes are taking the "static propTypes" declaration off
of components and declaring them as Flow types. Sometimes to support flow some
method signatures had to be added. There are some exceptions in which more had
to be done to tame the beast:
- AbstractVideoTrack: put in additional truthy checks for videoTrack.
- Video: add truthy checks for the _videoElement ref.
- shouldRenderVideoTrack function: Some component could pass null for the
  videoTrack argument and Flow wanted that called out explicitly.
- DisplayName: Add a truthy check for the input ref before acting on it.
- NumbersList: Move array checks inline for Flow to comprehend array methods
  could be called. Add type checks in the Object.entries loop as the value is
  assumed to be a mixed type by Flow.
- AbstractToolbarButton: add additional truthy check for passed in type.

* feat: Displays the server region in the stats panels.

* feat: Displays the server count in the local stats panel.

* ref: Renames a variable.

* fix: Makes bridgeCount a number, clarifies docs.

* chore: Updates lib-jitsi-meet to 1ac6df97e3.

* feat: Displays the E2E RTT in the connection stats table.

* fix: Whitelists the ping config properties.

* ref: Addresses feedback.

* npm: Updates lib-jitsi-meet to e097a1189e.

* ref: Moves the e2ertt and region to the existing stats object.

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.

* ref(connection-stats): use PropTypes package

* feat(connection-stats): display a summary of the connection quality

* feat(connection-indicator): show empty bars for interrupted connection

* feat(connection-indicator): change background color based on status

* feat(connection-indicator): implement automatic hiding on good connection

* fix(connection-indicator): explicitly set font size

Currently non-react code will set an icon size on ConnectionIndicator.
This doesn't work on initial call join in vertical filmstrip after
some changes to support hiding the indicator. The chosen fix is
passing in the icon size to mirror what would happe with full
filmstrip reactification.

* ref(connection-stats): rename statuses

* feat(connection-indicator): make hiding behavior configurable

The original implementation made the auto hiding of the indicator
configured in interfaceConfig.

* fix(connection-indicator): readd class expected by torture tests

* fix(connection-indicator): change connection quality display styling

Bold the connection summary in the stats popover so it stands out.
Change the summaries so there are only three--strong, nonoptimal,
poor.

* fix(connection-indicator): gray background on lost connection

* feat(icons): add new gsm bars icon

* feat(connection-indicator): use new 3-bar icon

* ref(icons): remove icon-connection and icon-connection-lost

Both have been replaced by icon-gsm-bars so they are not
being referenced anymore. Mobile looks to have connect-lost
as a separate icon in font-icons/jitsi.json.

* feat(small-video): use InlineDialog for stats and remote menu

- Remove JitsiPopover and use InlineDialog instead.
- Bring the remote menu icon into react.
- Make vertical filmstrip position:fixed so popper (AtlasKit
  dependency) sets InlineDialogs and eventually tooltips to
  position:fixed.

* ref(remote-menu): hook KickButton to redux

* ref(remote-menu): hook MuteButton to redux

* modify padding, toggle dialogs

* pixel push margins to align dialogs, adjust padding of dialogs

* add comment about margin for dialog, add file I forgot

* modify indicator markup so the icon can be moved down while trigger stays at top of toolbar

Move all logic related to displaying a table of connection stats to a React
Component. The actual parsing logic was modified as little as possible as the
focus is moving display to React.
