In some environments, puppetdb can take longer than 10 seconds
to start up. Prior to this commit, that value was hard coded
and the module would sometimes fail when it wouldn't have failed
with a slightly larger timeout. This commit makes the timeout
configurable, and also increases the default value to 15 seconds.
This commit does the following:
* Use the new inifile module to manage puppet.conf
* More comprehensive management of config files
* Validate database connectivity before applying puppetdb
config changes
* Validate puppetdb connectivity before applying puppet
master config changes
* Documentation
