feat(devservices): Support migrations in devenv sync for new devservices

[hubertdeng123]

For users using the new devservices, they should set the USE_NEW_DEVSERVICES in their .env file.

devenv sync will bring up new devservices in preparation for migrations. It will also bring down services brought up with sentry devservices since those will conflict with new devservices ports.

hmm I thought the plan was to make sentry devservices gracefully use devservices when available / used?

That was the plan, but we thought about it some more and decided against it because we wanted people to get into the habit of usingdevservices instead of sentry devservices. Additionally, working with click was pretty painful to get it to properly call devservices and pass in the appropriate args.

We can add a warning whenever users use sentry devservices if they have the USE_NEW_DEVSERVICES set to encourage them to use devservices instead for starting dependencies.

@asottile-sentry What do you think?
