(feat): docker-compose dry run + exit codes

[lukasmrtvy]

From: #1203

Personally I would like to see these features also ( for better machine parsing.. ):

• docker compose up -d --dry-run --exit-codes ( exit code: 100 -> will change, 0 -> will not change, 1 -> error )
• docker compose up -d --dry-run --diff ( show diff if ec = 100 )
• docker compose up -d --exit-codes ( exit code: 100 -> changed, 0 -> nothing changed, 1 -> error )
• docker compose up -d --exit-codes-in-json ( {"ec":"100"} , {"ec":"0"} , {"ec":"1"} )

Thanks
