Proposed changes

On deploy command, we are calculating which images have to be built. It might happen that there are not images to build e.g. no build section defined, or deploying just a subset of services from a compose with using public images. In that case, internal logic within the build function was considering that all the images had to be built. In most of the cases that wouldn't generate issues, but in other cases it would generate unnecessary builds.

For example, having a compose file like this:

services:
  foo:
    image: nginx
    volumes:
    - ./foo:/data
  bar:
    image: nginx
  baz:
    image: nginx

and the following okteto manifest:

deploy:
  compose:
    file: file.yml
    services: [bar, baz]

The Okteto manifest is considering to deploy 2 services that directly use a public image and there is no need to build.

If you deploy that manifest, you will see how the foo image is being built even if it is not necessary.

How to validate

Using the scenario described above, execute okteto deploy and see that foo image is not being build. Add that service within deploy.compose.services, execute it, and see how the image is now build. (it is expected that the build of foo fails because the folder foo doesn't exist

Without these changes, the first deploy would have triggered the deploy, and it shouldn't
