[sjinks]

Description

This PR adds support for cron (cron-control-runner) to the dev env.

~Depends on: Automattic/cron-control-runner#26~ ~Depends on: Automattic/cron-control-runner#27~ ~Depends on: Automattic/vip-container-images#783~

(it still can run without the PRs above; the only difference is that the system cron daemon will be used instead of cron-control-runner)

It introduces a new option to vip dev-env create and vip dev-env update:

    -c, --cron                    Enable or disable cron, disabled by default. Accepts "y" (default value) to enable or "n" to disable.
