High: mysql: do not report success on 'stop' if validation fails
High: mysql: report error when validation fails during monitor yet pid is still active
High: mysql-common: avoid use of check_binary in common validation function.

Since the environment validation exit code needs to be interpreted
differently now for monitor operations, we need to avoid functions like
'check_binary' that exit the process immediately upon failure. Instead
we should use 'have_binary' in this situation.

This allows the mysql agent to work properly in a scenario where the entire
mysql install resides on shared storage.
Low: VirtualDomain: downgrade error msg during probe

An error to find a domain's emulator does not indicate an error
during the probe operation. This situation is only an issue
if it occurs during a recurring monitor operation after a successful
start has occurred.

High: docker: properly remove stale container during stop when 'reuse' is not enabled
High: docker: replace 'container' argument with 'name'

I realized that the 'container' argument means something special in
pacemaker. In order to avoid confusion, the 'container' argument for
this agent has been changed to 'name'. Anyone using 'container' as
an argument right now will not be affected. The option still works, it
is depreciated now though.
