* Remove testing with 9 and 10 as they are no long supported

* Refactor installation, configuration and service resources

1. Condense client_install, server_install and respository resource into
   a single install resource.

2. Remove service action from install to remove the ability to enter a
   pathological situation where the chef run will not complete due to
   the service not starting because of a config error but the config error
   is unable to be corrected to allow the service to start.

3. Refactor the server_conf resource to config and add
   load_current_value support.

4. Initial work to switch back to pg gem instead of shell_out for SQL
   controlled resources. (may revert)
