Add flag similar to --pull always

[maximkosov]

We are using devcontainer cli tools with dockerComposeFile. Our compose file has a number of dependency images.

Docker compose has docker compose --pull always flag that will

1. Pull images if compose file was changed
2. Re-create containers only for the services which images were changed

Unfortunately there're no alternatives in devcontainer cli tools:

• We can use docker compose pull && devcontainer up but it won't re-create updated services;
• We can use docker compose pull && devcontainer up --remove-existing-container but it will recreate the main (i.e. devcontainer) service even if image wasn't changed. We want to avoid re-creating the main service every time because it runs long postCreate scripts.

Is it possible to provide flag similar to --remove-existing-container that will be translated to --pull always that will recreate only changed services?
