This commit adds a test that demonstrates that a client is unable to continue backing up states to the server if any session errors occur. This will be addressed/fixed in the upcoming commits.
Let the StopAndRemove method return false if a session with the given ID was not found in the queue set. This will be used in an upcoming commit.
A new CSessionBorked status is to represent a session that is should be seen as permanently inactive. Various methods are also updated: - The isSessionClosable methods are updated so that sessions need to be either exhausted _or_ borked in order to considered closable. - The ExhaustedSessionFilter function is also updated to filter out borked sessions. - The markSessionStatus method is updated to make sure that a session marked as borked cannot be marked as inactive or active.
In preparation for the use of this variable in other packages, it is exported in this commit.
Add a new MarkSessionBorked method to the wtclient DB and add a test to assert the behaviour.
This commit adds a Stopped method to the sessionQueue which returns a channel that can be listened on for a signal that the queue has stopped its operations. This tells the backupDispatcher that it should pick or negotiate a new active session queue.
This commit adds the MarkSessionBorked method to the TowerClient and then demonstrate in a test that this method allows a user to force the abort of an erroring session so that a new one can be negotiated.

With this PR, watchtower clients now have the ability to force a session to be
marked as "borked". This means that if the server ever returns session errors
that cause updates to not be backed up (like in #6397), the a user can force
the session to be aborted.
