Bug Description

As detailed by the build artifacts of the gate failures in https://review.opendev.org/#/c/744402/ the octavia units go OOM while running in the gate.

What happens is that the policyd functional test add/remove policy file resources, and juju's behavior for handling that is to run a upgrade-charm hook.

The Octavia charm is using the reactive framework, and a upgrade-charm event for a reactive charm means rebuilding the charms wheelhouse.

Rebuilding a charms wheelhouse some times means compiling binary code, and is this instance there just is not enough memory to do it because of all the services running etc.

    Increase available cores and memory for octavia unit

    The charm Octavia gate job has started to OOM for the Octavia
    units as detailed on the bug.

    This change addresses both that issue and attempts to increase the
    velocity of the test by adding CPU cores which might help for the
    time it takes to compile binary dependencies on initial deploy
    and during the policyd tests.

    Note that instead of explicitly mentioning amount of memory we
    assume a flavor with more cores to also have more memory.
