[MDEPLOY-206] Deploy improvements (#38)

Changes:
* remove deployInParallel, deploy plugin when deployAtEnd always creates one deploy request and passes it to resolver
* remove misleading log "deferring deploy" when the module is actually last and is not deferred by deploys all
* Remove obsolete IT
