Add common commands to deploy hook

[gilzow]

What in this template can be improved or added as a feature?

during a deploy we should go ahead and attempt a cache flush, db update, and run crons that are due as any/all of those items may have been affected during the build.

What exactly should be updated?

    deploy: |
        wp cache flush
        wp core update-db
        wp cron event run --due-now

How important is this feature to you?

it'll be one less things user need to deal with
