Metadata parser

[rskumar]

Many Idp provides required info for client setup in metadata available at some URL.
It would be great if a utility method is provided to parse metadata content (as string), access individual attrs and values in OneLogin_Saml2_Metadata class.

Example:

metadata = OneLogin_Saml2_Metadata.parse_metadata_from_url(url)
metadata.entity_id
....
# or/and
OneLogin_Saml2_Metadata.parse_metadata_content(str_content)

Our ruby-saml toolkit currently supports a way to extract data from an IdP-metadata:
https://github.com/onelogin/ruby-saml/blob/master/lib/onelogin/ruby-saml/idp_metadata_parser.rb

We will consider to extend this functionality to the rest of our toolkits.
