Merge branch 'permanent-delete' into 'master'

Permanent delete API modification

## Purpose
> Delete multple devices from one API call.

## Goals
> Avoid invoking the API multiple times to delete a set of devices.

## Approach
> Delete the records of the devices as batch operations in the core level via a DEeviceDAO object and in the plugin level by creating a DeviceManager object for each device type.

## Documentation
> N/A

## Automation tests
 - Unit tests 
   > None
 - Integration tests
   > None

## Security checks
 - Followed secure coding standards? (yes)
 - Ran FindSecurityBugs plugin and verified report? (no)
 - Confirmed that this PR doesn't commit any keys, passwords, tokens, usernames, or other secrets? (yes)
