Closes#6382
Create SetUserVarsAccountsToReconnectCommand.
This command loops on all workspaces and:
- deletes all user vars with deprecated key `ACCOUNTS_TO_RECONNECT`
- creates a key value pair of type `USER_VAR` with a key of
`ACCOUNTS_TO_RECONNECT_INSUFFICIENT_PERMISSIONS` for all connect
accounts with a message channel or calendar channel with status
`FAILED_INSUFFICIENT_PERMISSIONS`
