Ashutosh Mestry updated ATLAS-2461:
-----------------------------------
    Description: 
*Background*

As part of data migration, earlier versions of Atlas (prior to v 1.x) should be 
export contents of their database to a ZIP file, that would later be imported 
into a cluster running new version.

During this process, the server should not accept any requests or process 
notifications.

This process should work on an existing cluster without making it necessary to 
upgrade.

*Approach*

Create a command line utility that would perform export using core components 
from Atlas. This would allow Atlas to be shutdown, so that it does not process 
any incoming requests or hook messages.

This utility should allow for using external configuration JSON so that it can 
be used on Atlas setup that does not have latest version.
