Will try to use screensharing instead of camera video from
the beginning.

* Fix(AddPeopleDialog): Fixes error state and close dialog

* (to-squash) Addresses comments

Add a menu that displays when hovering over VideoStatusLabel. The menu's
display is controlled by CSS. As the existing AudioOnlyLabel no longer needs
needs its own tooltip, it has been removed and label display logic has been
moved into VideoStatusLabel.

DialInNumbersForm has been modified to display a conference id to be used for
dialing into the conference. The changes include:
- Requesting the conference id and adding the conference id to the redux store
- Displaying the conference id in DialInNumbersForm
- Modifying the copy behavior to support copying the new message to clipboard
- DialInNumbersForm does not display until all ajax requests have completed
  successfully. This eliminates the need for the REQUESTING state.

Device selection has live previews that reuse the current local
audio and video tracks for the sake of internet explorer. This
means when the local video was muted, device selection would
show a muted message. It is preferred to show a live preview
even when muted.

The changes include:
- Passing device ids into DeviceSelectionDialog, not tracks.
- Setting default selected devices to use for live previews.
- Removing all checks in DeviceSelectionDialog involving local tracks.
- Catching and displaying errors when creating a live video preview.

Audio only mode can be used to save bandwidth. In this mode local video is muted
and last N is set to 0, thus disabling all remote video.

When this mode is enabled avatars are shown.

* fix(react/participant): store display name in redux

* feat(remotecontrol): Add option to display the authorization dialog in meet

* feat(remotecontrol): Enable ESLint and Flow

Create a new React Component for displaying a list of dial-in
numbers. The Component will fetch the numbers from a new
numberRetreviewUrl key/value set in config. If not present in
config, the Component will not be displayed.

AtlasKit DropdownMenu cannot be disabled, unlike Single Select.
The result is the isDisabled prop was not being honored. The
workaround is returning only the trigger element for the dropdown
and styling it to look like the dropdown is disabled. The text
for disabled device selection was changed along the way to fit
into the trigger.

Converting the invite modal includes the following:
- Creating new react components to display InviteDialog. The
  main parent components are ShareLink and PasswordOverview,
  the later handles displaying lock state and password editing.
  These components do not make use of atlaskit as the component
  for input does not yet support readonly, so for consistency
  within the modal content no atlaskit was used.
- Using redux for keeping and accessing lock state instead of
  RoomLocker.
- Publicly exposing the redux action lockStateChanged for direct
  calling on lock events experienced on the web client.
- Removing Invite, InviteDialogView, and RoomLocker and references
  to them.
- Handling errors that occur when setting a password to preserve
  existing web funtionality.

Device Selection re-uses the local video track for its preview.
When displaying Device Selection while video muted, the text
"muted" displays within the video preview, but some translations
may mistake this to mean audio muted. The text has been changed
to be explicit about video mute. This is a temporary solution;
at some point Device Selection should not re-use the local track
except for IE, the one browser that cannot get multiple tracks
from the same video input.

Fix spelling/grammar for  micConstraintFailedError and cameraConstraintFailedError

The Device Selection modal consists of:
- DeviceSelection, an overly smart component responsible for
  triggering stream creation and cleanup.
- DeviceSelector for selector elements.
- VideoInputPreview for displaying a video preview.
- AudioInputPreview for displaying a volume meter.
- AudioOutputPreview for a test sound output link.

Store changes include is primarily storing the list of
available devices in redux. Other app state has been left
alone for future refactoring.

Moves the P2P indication next to the remote IP address
and rewords it to "(p2p)".

#1411

Will show (direct) next to the UPD or TCP transport type if we're
running on P2P connection.

* Handle last n in the client

* fix(LargeVideoManager.js): Fixes check for low bandwidth. Needs more work

* fix(LargeVideoManager.js): Fixes the Shared Video test.

* fix(LargeVideoManager): Fix shared video view and remove last n checks.

* fix(LargeVideoManager): Fixes jsdoc comment

* fix(RemoteVideo): Fix connection status check

* fix(LargeVideoManager,RemoteVideo): Syntax errors

Firefox (at least) renders it verbatim.

Updates transport type to show multiple values as we do for addresses and ports.

Split language detectors to be web/native dependent. Take care of strings that contain html.

Removing translateString forces using data-i18n attributes, to make sure we do not forget to set them. Missing data-i18n attributes is a problem with late loading where we can end up without translation, without text. Missing data-i18n attributes is also problem that strings will not be translated when changing language.
Fixes a bug in invite dialog, where remove password button was shown for non moderators.

Will disconnect on ConferenceErrors.VIDEOBRIDGE_NOT_AVAILABLE.
Show the same message when either JVB is not available or Jicofo
disconnects.
