Ambari server upgrade does not re-extract the jar content of the views

STR:

1. Upgrade ambari-server from 2.0.0 to 2.1.0
2. Start ambari-server

Actual Result: All view's jar are updated but previously extracted web resources are not updated
Expected Result: All view's jar should be updated and views resources should be explicitly extracted to update the web content

Due to this issue, user gets in a situation where views backend is updated but frontend is still using stale bits of earlier version which results in completely broken view in some cases.

workaround:
Manually stop ambari-server.
Move the web resources of view to another location
Start ambari-server back. This will re-extract the jar content and new web resources of the updated ambari version will be then used.
