gRPC doesn't have a handler for recovering from a panic like a normal
HTTP request so a panic will actually kill Vault's listener. This
basically copies the net/http logic for managing this.
The SSH-specific logic is removed here as the underlying issue is caused
by the request forwarding mechanism.

* Respond to PR feedback
In auth/aws/config/client, when only the iam_server_id_header_value was
being updated on an existing config, it wouldn't get stored because I
was trying to avoid unnecessarily flushing the cache of AWS clients, and
the flag to not flush the cache also meant that the updated entry didn't
get written back to the storage. This now adds a new flag for when
other changes occur that don't require flushing the cache but do require
getting written to the storage. It also adds a test for this explicitly.
Fixes#3004
