This MR adds a Lua test suite to the project, run via busted, and introduces tests for a number of the utility functions. Subsequent work will have to be done to test functions that use the `vim.api` scope and external packages to the plugin.
This MR is a #patch fix that ensures you can provide a `.gitlab.nvim`
file at the root of the git project and open up the reviewer at any
level of the project.
This MR adds the `.pipeline()` command which opens up the pipeline popup. This popup shows information about the current pipeline and it's jobs, and gives users the ability to re-trigger failed jobs.
