Context:
In order to manage event based processes we need a CRUD API for those.

AT:

• there is a new top level eventBasedProcess api endpoint that allows to
  • create an eventBasedProcess
  • update an eventBasedProcess
  • delete an eventBasedProcess by id
  • get and eventBasedProcess by id
  • list all available eventBasedprocesses (do not include xml)
• the properties of an eventBasedProcess are
  • id (created on creation)
  • name
  • xml
• eventBasedProcess entities are stored in a new index
• documentation is updated to include new API
