EDGAR should support using custom bridge name in Managed Mode

[mbfm]

EDGAR should support using a custom bridge name. See #55 for context.

This name should be specified via LEA and CLEO and passed into the PeerDescriptor.
From there, CARL should transfer it into the PeerConfiguration, which gets passed down to EDGAR.
EDGAR can then use this information during setup of the bridge.

This depends on #23.

We've noticed that this requires an architectural change to cleanly handle removing a pre-existing bridge. Not removing the bridge could lead to network traffic being misdirected.

For now, we could integrate it with a disclaimer or potentially error handling, so that users don't change it after creating a peer.
Might be easiest to simply block such a change in CARL and only offer the UI in CLEO.
