JBTIS-83 - Adding ESB examples plugin

i think the version number should match jbtis not JBDS when it is community and tied to jbtis name.

Thus 7.1 seems in appropriate here. should match esb or jbtis version imo to be consistent.

Also if this points to master in the beta1 branch that means any change here is instantly available on both branch and master. You won't be able to experiment or do changes to this file without affecting all installs.
