Adapt to E2EE changes in lib-jitsi-meet. Notably:
---
e2ee: introduce per-participant randomly generated keys
This the second stage in our E2EE journey.
Instead of using a single pre-shared passphrase for deriving the key used for
E2EE, we now establish a secure E2EE communication channel amongst peers.
This channel is implemented using libolm, using XMPP groupchat or JVB channels
as the transport.
Once the secure E2EE channel has been established each participant will generate
a random 32 byte key and exchange it over this channel.
Keys are rotated (well, just re-created at the moment) when a participant joins
or leaves.
---
* Add dialog to set the E2EE key
* Use the Redux action / middleware to update the key even when set through the
hash parameter
* Cleanup URL after processing the key so it's not recorded in browser history
