dump console if we time out on a server op

if we timeout waiting for a server to do a thing, also dump the
console before we raise the exception. This will hopefully help
on debugging failures.

Place baremetal common methods in base class

This is part 1 of a change to add advanced operations tests for
the ironic baremetal tests. This moves some methods, currently
defined in the BaremetalBasicOpsPXESSH class, up to the base class
where they can be used by both basic and advanced tests. Advanced
test will be added in a separate review.

The ironic state definitions are also moved up to the manager.py
file where they can be easily accessed.

This also fixes a typo and renames BaremetalBasicOptsPXESSH to
BaremetalBasicOpsPXESSH.

Make run_stress.py script an entry point

With change f8b816af0751b10cc20b0ab456ca334150fcdf5f we started
packaging binaries using pbr entry points. The run_stress.py script
previously lived in tempest.stress, howver since it is intended to be
run as a binary the proper place for it is now tempest.cmd and using
an entry-point it will be easier to run it outside of the tempest
tree.

Add bug skip for test_container_synchronization()

This commit adds a skip to test_container_synchronization(). This test
currently only gets run during the periodic -all job because of it's
slow tag. It is currently failing 100% of the time and has been in this
state for quite some time. So let's skip it until the underlying bug is
fixed.
