test_create_servers by default creates floating IPs

[Ryan Rossiter]

It looks like this change (https://review.openstack.org/#/c/149229/) added in ssh validation for server creation tests. This change by default uses floating IPs to test the validation, even if CONF.compute.run_ssh is set to false.

The default behavior is to use floating IPs with SSH validation, so without a floating IP pool, tests that use ssh validation will fail. It looks like there is no option within the validation section to turn validation off, so setting validation.connect_method to fixed is necessary to keep fixed IP Tempest-ing working.

    Add new config option to globally trigger resource validation

    This commit adds a new config option to the config group to trigger
    all the validation code. It also deprecates the run_ssh option in the
    compute group since this will eventually be used globally. The intent
    of this option is so that it will trigger both the creation of any
    validation resources as well as used as run_ssh was originally
    intended, to trigger ssh into nodes when needed.
