add versioned migrations

Up until this commit, headscale has had one massive migration func that runs every time the server starts. This means that every time we have migrated anything, we have added stuff to it and not really taken into account how the database of clients look like. This means that sometimes the new stuff has had to be added in the middle, as it would break things further down. It is kind of a miracle that it has worked so far with no permament damage, particularly considering some of our larger migrations like Machine -> Node or Namespace -> User. This commit addresses this by adding gormigrate, which is a simple versioned migration system. As we have to maintain our messy past, the first migration is the large, currently working, but hard to change function. Subsequent changes should be added with new IDs after this.
