Move CONF.service_available.ironic to our plugin

This is unwanted in tempest's plugin, bring it here instead.

Also add skip checks for our tests to skip the tests if ironic is not
enabled. This allows the plugin to be installed in a tempest
environment, without breaking if ironic isn't present.

Last, drop 'baremetal' from the test.services decorators used, as it is
no longer in tempest's service list, and we use the skip check mentioned
above instead.
