Thomas Eizinger be1a719e2c chore(relay): perform graceful shutdown upon receiving SIGTERM (#4552)
Upon receiving a SIGTERM, we immediately disconnect from the websocket
connection to the portal and set a flag that we are shutting down.

Once we are disconnected from the portal and no longer have an active
allocations, we exit with 0. A repeated SIGTERM signal will interrupt
this process and force the relay to shutdown.

Disconnecting from the portal will (eventually) trigger a message to
clients and gateways that this relay should no longer be used. Thus,
depending on the timeout our supervisor has configured after sending
SIGTERM, the relay will continue all TURN operations until the number of
allocations drops to 0.

Currently, we also allow clients to make new allocations and refreshing
existing allocations. In the future, it may make sense to implement a
dedicated status code and refuse `ALLOCATE` and `REFRESH` messages
whilst we are shutting down.
