gh codespace and git status wrappers

[isedwards]

Implement a wrapper around GitHub CLI's gh codespace and git status -s:

1. opencdms codespace status - show git status -s for all git repositories in /workspaces/

   Wrap the command below in Python

   find /workspaces -type d -name '.git' | while read dir ; do sh -c "cd $dir/../ && echo \"${dir//\.git/}\" && git status -s" ; done
   

   ... and only display lines starting with / if the next line does not start with '/'.

2. opencdms codespace delete - delete current codespace if no changes in any repos in /workspaces/

   We can delete the current codespace container with:
   gh codespace delete -c $CODESPACE_NAME

   Offer -f and --force options to kill the container even if code changes exist.

Note:

• Install GH cli with these instructions:

  type -p curl >/dev/null || sudo apt install curl -y
  curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg \
  && sudo chmod go+r /usr/share/keyrings/githubcli-archive-keyring.gpg \
  && echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null \
  && sudo apt update \
  && sudo apt install gh -y
