[Feature Request]: Before delete check that can be deleted

[tyoc213]

Describe your idea/feature/enhancement

Before delete check that can be deleted..

Proposal

For each thing, it should check if is possible to delete like:

• an s3 not being able to be deleted because not empty
• a subnet because used by something that is not controlled by copilot
• a network interface used by a lambda

Additional Details

Deleting things when failing becomes a hunt to see what is going on and do things "manually" or try to put again the env/src/job again and delete it to see if it works.

Guess it is more work, but will be nice to know or have better descriptive/exact outputs of what/why failed.
