glusterd: import volumes in separate synctask
With brick multiplexing, to attach a brick to an existing brick process the prerequisite is to have the compatible brick to finish it's initialization and portmap sign in and hence the thread might have to go to a sleep and context switch the synctask to allow the brick process to communicate with glusterd. In normal code path, this works fine as glusterd_restart_bricks () is launched through a separate synctask. In case there's a mismatch of the volume when glusterd restarts, glusterd_import_friend_volume is invoked and then it tries to call glusterd_start_bricks () from the main thread which eventually may land into the similar situation. Now since this is not done through a separate synctask, the 1st brick will never be able to get its turn to finish all of its handshaking and as a consequence to it, all the bricks will fail to get attached to it. Solution : Execute import volume and glusterd restart bricks in separate synctask. Importing snaps had to be also done through synctask as there's a dependency of the parent volume need to be available for the importing snap functionality to work.
