Bug 999295: Improve mongodb startup verification reliability

Ensure that mongodb is actually running after calls to `control start`, taking care to return
an error if it's not running. Prevent false-positive reporting of started state.
Bug 1002269 - empty client messages are dropped, should be new line
Status was failing at the curl command on stopped gears due to the -e
Disable the puppet repository for the mcollective packages. Otherwise the installation will fail

Give the option of installing the release version
Make available the option even for splitted broker/node option
