New Hook for SAPDshell

SAPDshell is a node.js based application that triggers source code deployment from Github repositories to SAP HANA.
With this we want to enable GitHub Users to develop for SAP HANA much moir easily

Calling SAPDshell needs via Service hook means handling over user/password and providing the url of the SAPDshell (We might have different once). 
Additionally Github user and repository url is taken from payload to generate caller URL and execute http request.

Please check and include into list of Service Hooks.

Kind Regards
Joerg on behalf of the Dshell team
