This refactors resource dependencies to improve the following points.
- Avoid unnecessary dependencies across services. For example aodh
service does not require cinder db.
- Restart only api service when config files like paste.ini, which
are used only be api service is changed.

This patch is adding the configuration of the number of workers,
threads, and the size of the listen queue in Debian, which uses
uwsgi to run Heat API and api-metadata. Therefore, this patch adds
two new heat_api_uwsgi_config and heat_api_cfn_uwsgi_config
providers as well as two new heat::wsgi::uwsgi_api and
heat::wsgi::uwsgi_api_cfn classes.

Previously the anchors and dependencies that allow external hooks were
all in the main ::heat class. However, if you wanted to include just
::heat::db::mysql, then it would fail, since it assumed the main heat
class was included. This moves all of those resources and relationships
into a new class, ::heat::deps. All of the classes will now include
this class so that the anchors and deps are always evaluated even if
only a portion of the classes are used, and even if ::heat isn't pulled
in.
