The call url is an anchor element so that right clicking it
can bring up the copy link option in the context menu.
Clicking on it does a no-op so the anchor was colored to
look like plain text. Hovering over it right now makes it
look like an anchor due to some atlaskit color, so supress
the coloring.

* fix(info): bold info labels

* fix(info): do not truncate url

* feat(info): show only during a lonely call

* feat(invite): be able to call numbers from the invite dialog

The major changes:
- Remove DialOutDialog, its views, redux hooks, css, and images.
  Its main functionality has been moved into AddPeopleDialog.
- Modify the AppPeopleDialog styling a bit so it is wider.
- Add phone numbers to AddPeopleDialog search results. Phone
  numbers are validated in parallel with the request for people
  and then appended to the result. The validation includes
  an ajax to validate the number is recognized as dialable by
  the server. The trigger for the validation is essentially if
  the entered input is numbers only.
- AddPeopleDialog holds onto the full object representation of
  an item selected in MultiSelectAutocomplete. This is so
  selected items can be removed on successful invite, leaving
  only unsuccessful items.
- More granular error handling on invite so individual invitees
  can be removed from the selected items list.

* squash: change load state, new regex for numbers

InviteDialog functionality has been moved into InfoDialog.

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.

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.

@virtuacoplenny, the changes of this commit are not necessarily in
source code that you introduced in
https://github.com/jitsi/jitsi-meet/pull/1499 but I saw violations in
files modified in the PR which I had to read in order to understand the
PR.

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.
