This service runs in a VM and is responsible for:
1. Determining which PRs need to be analyzed
2. Running mkcmp against each PR
3. Commenting the results on the PR via minikube-bot
This PR also moves the mkcmp code into its own directory.
This PR adds a skeleton for mkcmp, a binary to compare the performance
of two versions of minikube. It adds a Makefile rule out/mkcmp which
builds the binary.
