New Upgrade Scenario for MongoDB Engine Upgrade from MMAPv1 to WiredTiger

[devendra104]

I would like to add Mongo storage engine upgrade test scenario in the current upgrade(Satellite, Capsule, and CustomerDB upgrade) workflow. There is no impact on the current workflow if we include it and will achieve both the things (upgrade and mongo DB engine upgrade) in a single attempt.
We will keep it separately in current upgrade workflow and it will be executed in end of the upgrade. Mongo DB engine upgrade treats as an optional parameter, If the user wants to test MongoDB Engine upgrade along with upgrade then pass the optional parameter(like foreman-maintain, puppet version) in the current workflow.

In this release, We have observed 8 to 9 bugs which were related to this feature.
As of now, mongo DB engine upgrades as an optional parameter of an upgrade and by default it uses MMAPv1 mongo DB engine.

@devendra104 is it part of upgrade process now or do we need to include in CI/any task?
