Service hook

Registered by Kanagaraj Manickam on 2016-04-18

Most of the openStack services use oslo.service to launch their components including api and backends. It provides to launch the comonent with 1+ workers. Sometime cloud operators wants to do their actions before and after starting the components based on their needs . so this blueprint is filed to incorporate such features in oslo.service projects.

As the pre and post actions are dynamically available, its better to make them as configurable as below:

[oslo_service]
List of of pre-hook executed in sequence
pre-hook=<comman separated pyton module used as hooks>
List of of pre-hook executed in sequence
post-hook=<comman separated pyton module used as hooks>

And make sure, the hooks run between try... except .... to make sure this does not break the service startup/stop.
