Add a repository_setup.sh script that automates a couple of setup steps
for setup of new rust-vmm repositories. It also supports updating the
configuration of already created repositories by comparing the
repository's configuration to the defaults in rust-vmm-ci and giving the
option to update.
Currently, the script supports dependabot setup and .platform file
generation. It does not deal with the coverage files, since I am still
hoping to switch us over to codecov.io in the future, at which point
that will all changes completely anyway.
