As of compute microversion >= 2.21, support for list and show of server
events for deleted servers was added. This however wasn't working using
the openstackclient because the compute GET /servers/{server_id} will
not return a deleted server, so osc_lib.utils.find_resource() fails to
find the server and the command bails early.
This adds a check for a uuid-like <server> arg and uses it directly if
the <server> cannot be found via find_resource().
A note is also added to the command help to indicate that list and show
for deleted servers will only work if a server ID is passed (name will
not work).

Move common bits into a compute.v2.common.ComputeTestCase class
so they are available as needed without calling into other test
classes.

OSC server event is similar to nova's instance action commands.
Server event is the event record that had been done on a server,
include: event type(create, delete, reboot and so on),
event result(success, error), start time, finish time and so on.
These are important information for server maintains.
