Fixes issues with phobos (all methods currently implemented functional)
Fixes issues with the sample apps
Creates a job which allows us to schedule a nightly build of hestia with motr and phobos plugins, and test the phobos plugin.
Adds a job which if enabled will create a MR to master if nightly build passes.
Adds a manual job which will only run on master, which currently publishes the hestia RPM to package repo but in future will also tag a release of Hestia.
