Introduce PINGABLE and SSHABLE waiters and wait_until state support

This change introduces two new instance state waiters and uses them to
extend the existing tempest.common.compute.create_test_server wait_until
state support.

They are being introduced in an effort to allow the guest OS time to
start *before* we start attempting to interact with it either directly
by connecting to the instance or indirectly by hot-plugging or
hot-unplugging devices. The latter on some virt backends being an issue
if the guest OS is unable to respond to the underlying ACPI requests
sent to it.

It should be noted that these new states rely on the instance already
being ACTIVE before we begin to wait for the instance to either become
pingable or accessible over SSH. This is taken into account and will
always happen for these states even if validation isn't enabled in the
environment and thus it isn't possible to wait until the instance is
pingable or accessible over ssh.
