Remove bind9 and add functional tests

This commit moves the installation of bind9 to the tests, leaving the
installation/configuration of the desired DNS server to the deployer.
We can eventually use a role to handle the installation/configuration
of bind, but some further research will need to be done to isolate
the best role.

Additionally, this commit adds some very basic tests that validate the
Designate API.  Next steps involve using designate-tempest-plugin to
handle this.

NOTE: No relnote is being added for the removal of bind9 as no valid
      configuration was being dropped for bind9, meaning we had a
      non-functional DNS server as far as designate was concerned.
