[PATCH v2 0/5] Honour and Document --no-gpg-sign

The subcommand `git commit` supports a `--no-gpg-sign` argument, which is useful incases where e.g. a GPG key is specified in `.gitconfig`, but is located on a hardware key that may not currently be attached to the system.

Multiple commands that understand --gpg-sign but haven't understand --no-gpg-sign, yet.

Also, document more commands that honours --no-gpg-sign

Change since v1:
- FREE_AND_NULL as soon as possible
- update test code for rebase --no-gpg-sign
- revert (--edit which is default in tty) now honours --no-gpg-sign
- cherry-pick --edit now honours --no-gpg-sign
- add more documentation
