// if the ExplicitPath, return the unmerged explicit file
// Otherwise, return a merged config based on the Precedence slice
// A missing ExplicitPath file produces an error. Empty filenames or other missing files are ignored.
// Read errors or files with non-deserializable content produce errors.
// The first file to set a particular map key wins and map key's value is never changed.
// BUT, if you set a struct value that is NOT contained inside of map, the value WILL be changed.
// This results in some odd looking logic to merge in one direction, merge in the other, and then merge the two.
// It also means that if two files specify a "red-user", only values from the first file's red-user are used. Even
// non-conflicting entries from the second file's "red-user" are discarded.
// Relative paths inside of the .kubeconfig files are resolved against the .kubeconfig file's parent folder
// and only absolute file paths are returned.
