Metadata url config parameter
Support for separate metadata url.

- Reverted some changes that are not relevant for the metadata url that were part of Jozef's branch.
- Changed name of the config property to MetadataLocation.
Documentation for metadataUrl config parameter.
- Changed name of the configuration to metadataUrl to match that of the federation configuration.
- Updated documentation with new metadataUrl config option.
Adding support for separate metadata url to idp.
