Description of problem:

Customer wants to use different users for Task operation and for REST authentication. But its not working with BPMS 6.2 release, it fails with below exception:

org.kie.remote.client.api.exception.RemoteApiException: The user id used
when retrieving task information (user1) must match the authenticating
user (user2)!

This was reported as bZ#1265568 but was closed as a "NOT a BUG".

However,several customer needs to get this use case to work.
In fact, the following system property is prepared to bypass this restriction

-Dorg.kie.task.insecure=true

but it does not work yet as expected.

Version-Release number of selected component (if applicable):
6.2.0

Steps to Reproduce:
1. Use one user credentials when using remote APIs
2. Try to get tasks for another users.

Actual results:
org.kie.remote.client.api.exception.RemoteApiException: The user id used when retrieving task information (user1) must match the authenticating user (user2)!

Expected results:
It should be possible somehow bypass this check to allow testing processes with tasks assigned to different users.
