Flux 1.11.0

This release comes with experimental garbage collection and Git commit signing:

1. Experimental garbage collection of cluster resources. When providing the --sync-garbage-collection flag, cluster resources no longer existing in Git will be removed. Read the garbage collection documentation for further details.

2. GPG Git commit signing, when providing --git-signing-key flag. GPG keys can be imported with --git-gpg-key-import. By default Flux will import to and use the keys in ~/.gnupg. This path can be overridden by setting the GNUPGHOME environment variable.

   Commit signature verification is in the works and will be released shortly.
