Support --name for all configurations

[r4victor]

The PR:

• Adds -n/--name to dstack apply for all configuration types. This is primarily relevant for [Feature]: Support per-job volumes #2264 so that it becomes easy to create many volumes using a one liner: for i in {0..7}; do dstack apply -f .dstack/confs/volume.yaml -n data-volume-$i -y; done.
• Improves dstack apply -h output: a hint to pass configuration type. If a configuration type is specified, prints configuration-specific options in a separate argument group:

dstack apply -h
Usage: dstack apply [--project NAME] [-h [TYPE]] [-f FILE] [-y] [--force] [-d]
                    [-P REPO] [--repo-branch REPO_BRANCH] [--repo-hash REPO_HASH]
                    [--no-repo] [-t OAUTH_TOKEN] [--git-identity SSH_PRIVATE_KEY]
                    [--ssh-identity SSH_PRIVATE_KEY] [--local]

  -t, --token OAUTH_TOKEN
                        An authentication token to access a private Git repo
