Update endpoint for saving UUIDs in Inventory ES app

Purpose/Overview:

The endpoint for saving UUIDs that match the search criteria will need to be updated so that there is no discrepancy between records returned by the search conducted using Elasticsearch and the number of records saved.

Scenario:

Given:  The search criteria pane is populated with results
When:  the user clicks on Save Instances UUIDs on the Action menu
Then:  UUIDs of records matching the search  are saved in the csv file.

Requirements/Scope:

Currently used endpoint:   /record-bulk/ids&query=keyword all "<search criteria> is replaced with the new one that is result of MSEARCH-93

Approach:

Acceptance criteria:

• The number of saved UUIDs is equal to the number of records matching search criteria
• Existing functionality of saving UUIDs doesn't change.
