Add charm-lp-recipe-sync.

charm-lp-recipe-sync job takes care of installing zosci-tools[0] and
running `zosci-lp-recipe sync` which reads osci.yaml to get the desired
charmcraft version to be used when building the charm and update the
Launchpad charm build recipe.

Introduces a new secret named "launchpad_token" which contains a token
associated to a uosci-testing-bot[1]
