Create new script for adjusting Pileup documents in MongoDB

[vkuznet]

Impact of the new feature
Simplify management of MSPileup records in MongoDB.

Is your feature request related to a problem? Please describe.
Due to implementation of partial data placement in #11807 we must adjust all pileup documents in MongoDB and add new transition record to them. To simplify this task we may create new script which will do just that.

Describe the solution you'd like
Create new script to adjust MongoDB records with the following logic:

• get all documents from MongoDB
• iterate through each document
• for concrete document create new transition record based on example of the code presented in this PR for createPileup API
• add new transition record
• update document in MongoDB

Describe alternatives you've considered
Can be done manuall in MongoDB, but this process may be tedious and error prone.
