Vincent Demeester 0bdf126d62 Add a new ExtractVariables function to compose/template package ...

It allows to get easily all the variables defined in a
composefile (the `map[string]interface{}` representation that
`loader.ParseYAML` returns at least) and their default value too.

This commit also does some small function extract on substitution
funcs to reduce a tiny bit duplication.
