Maid-315_update_data_manager_account_rebase

Based on the work from MAID-304.
1, trim DataManager account
2, update corresponding persona logical due to trimmed account in DM and PM
3, remove un-necessary class, action, etc.
4, comment out outdated tests
We can keep a copy of close_node_change in the persona and query it to check online/offline status.
Merging this pull request now as it is huge. But this comment should be resolved as a seprate sub task.
