Description

1. Removed RCF jars and updated to fetch RCF 3.0-rc1 from maven
2. Added zip and folder deletion before fetching zips for bwc and integCluster so there isn't multiple zips

I tested with rc1 that there is no bwc issues when creating real time single or multi entity detectors or for historical analysis on single and multi entity detectors.
