Takashi Kajinami 3bf5d9ed3c Refactor resource dependencies
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.

# Gnocchi anchors and dependency management
#
class gnocchi::deps {
# Setup anchors for install, config and service phases of the module. These
# anchors allow external modules to hook the begin and end of any of these
# phases. Package or service management can also be replaced by ensuring the
# package is absent or turning off service management and having the
# replacement depend on the appropriate anchors. When applicable, end tags
# should be notified so that subscribers can determine if installation,
# config or service state changed and act on that if needed.
