Currently DC orchestration divides the subclouds in stages and the
stage size is defined by the max_parallel_subclouds parameter or
by the size set for the group. Once a stage start being orchestrated,
it will wait for all subclouds of that stage to finish before starting
the next stage, causing the orchestrator to wait for slower subclouds.
The change is to remove the division by stage and keep adding a new
subcloud as soon as one finishes its orchestration in order to improve
the orchestrator speed.
Test Plan:
PASS: Create and apply a strategy with a specific subcloud and verify
that the orchestration finishes successfully.
PASS: Create and apply a strategy with a group of subclouds and verify
that the orchestrator uses the max_parallel_subclouds of that group.
PASS: Create and apply a strategy with max_parallel_subclouds
parameter and verify that the orchestrator uses that parameter.
PASS: Create and apply a strategy with stop_on_failure parameter and
verify that the orchestrator doesn't add any subclouds after the
failure is identified.
PASS: Create and apply a kubernetes strategy and verify that the
orchestration finishes successfully.
PASS: Create and apply a rootca strategy and verify that the
orchestration finishes successfully.
PASS: Create and apply a firmware strategy and verify that the
orchestration finishes successfully.
PASS: Create and apply a upgrade strategy and verify that the
orchestration finishes successfully.
PASS: Create and apply a patch with 100 subclouds in parallel
strategy and verify that the orchestration finishes successfully.
PASS: Create and apply a strategy with a group that has more
subclouds than the max_parallel_subclouds value and verify that
once a subcloud has been processed, another subcloud from
"unprocessed pool" takes its place.
PASS: Create and apply a strategy without specifying
--max_parallel_subclouds value having subclouds from different
groups that are elegible and verify that the orchestration
finishes successfully.
