Most errors that occur during preparing a session for a read/write transaction should be considered permanent, and should stop the automatic preparing of sessions. Any subsequent call to get a read/write session will cause an in-process BeginTransaction RPC to be executed. If
the problem has been fixed in the meantime, the RPC will succeed and the automatic prepare of sessions will start again. Otherwise, the error is propagated to the user.

Fixes #177
