| # Function to return an array of roles given the roles mapping, array of components and role types to lookup. |
| # Example map: |
| # $map = { |
| # component1 => { |
| # role_type1 => ["xxx"], |
| # role_type2 => ["yyy"], |
| # role_type3 => ["zzz"], |
| # } |
| # } |
| # calling get_roles(["component1"], ["role_type1", "role_type2"], $map) will return ["xxx", "yyy"] |
