Add Periodic MetalLB Bump workflow

This commit adds a new workflow to periodically align
with the upstream MetalLB repository.

This is setup to run daily at 7AM and 7PM, run the make `bump_metallb`
and if differences exist, then open a PR with the bump,
and on the commit message added details on the old commit,
and the new commit, just so it will be easier
for developers to maintain and keep track of changes.

Also deleted the `make test` from the bump_metallb, because we want
the workflow not to fail and to open PR even if the unit tests are
failing, so we could catch and fix that.
