Prevent slaves from executing actions on the master

Target

Configure Slave2Master access control for jenkins
Prevent Jenkins slave subsystem to access master and some restricted plugins.

Introduction

Historically, Jenkins master and slaves behaved as if they altogether form a single distributed process. This means a slave can ask a master to do just about anything within the confinement of the operating system, such as accessing files on the master or trigger other jobs on Jenkins.

Goals

• Turn on master to slave security in jenkins and provide new jenkins image
• Document how to extend this functionality in future (whitelist some plugins/files)
• Verify if slave can request or execute actions on master.
