This commit updates the two funtionalities of dcorch-api-proxy,
notify() and enqueue_work(), in order to ensure shared resource
changes are sync'ed timely post dcorch redesign.
The logic of the notify() method is updated to utilize the new
EngineWorkerService through an RPC call.
For a high number of subclouds, the enqueue_work method in utils.py
significantly delayed the execution of a dcorch proxy command due to
creating objects in the orch_request table one by one within a for
loop for each subcloud. This logic has been changed to use
SQLAlchemy's bulk_insert_mappings method, which allows for inserting
all requests in a single session. This optimization reduced the
execution time from several minutes to instantaneous.
Test Plan:
PASS: Run a command with '--os-region-name SystemController' on a
scale LAB. Verify that:
- The proxy creates the orchestration requests for each subcloud
in the `orch_request` table.
- The proxy updates the subcloud_sync table for the managed
subclouds, setting `sync_request` to 'requested'.
- The changes are synchronized to all the subclouds by the
`sync_job`.
- The delay for completing the proxy commandd is reduced
significantly.
