Support underscore in tags as plus replacement - #3

OCI doesn't really support semver as plus is not a valid character for tags. The spec may eventually add it: opencontainers/distribution-spec#154 But until then helm works around it with an underscore. By doing the same, we allow users to specify build identifiers in an OCI compatible way.
