tripleo: split network config control flags

[bogdando]

Add granular tripleo netconfig control flags

In local multi-cell setups, we use tripleo netconfig for cell stacks.
Extend it to the main stack as well.

In today multi-node CI we keep it disabled, so this
addition doesn't change the status quo.

Add a flag to managing tripleo default routes. This is
only used with tripleo dev setups, but may be extended to edpm dev
envs if needed.

Align the config download templates to use them consistently

Depends-On: https://review.rdoproject.org/r/c/rdo-jobs/+/55229

[bogdando]

testing it here https://review.rdoproject.org/r/c/testproject/+/53212 for multi-cell

Will test it with existing multinode jobs later

the testproject results look mostly OK now, just retriggering to get rid of intermittent errors
