This adds a ci wait subcommand, which will discover the version endpoint for a given project, and wait for it to update before exiting 0, or exit 1 if it exhausts the retries.

Example:

% CI_COMMIT_SHA=268de23asfasfd CI_PROJECT_NAME=psuid-service ./dist/devtool_linux_amd64/devtool ci wait -i foo -e develop
