Per suggestion from @jaimeperez, rename the undocumented
noconsentattributes option to be more consistent with other things and
with what has been done in the ConsentAdmin module. The old version
remains supported for backwards compatibility but issues a warning.

The Consent module has a (currently undocumented) noconsentattributes
option that allows specified attributes to be removed from the consent
hash calculation. The noconsentattribute option was introduced at
simplesamlphp/simplesamlphp@1efcfa8 but no corresponding option
was added to the consentAdmin module. Thus if people are using the
noconsentattribute option to remove attributes, the consentAdmin module
will *always* show this as attribute values having been changed.

This is a rework of simplesamlphp/simplesamlphp#531 which has gotten corrupted over time.

Change the extension of the documentation files from .txt to .md so that they can processed as markdown and displayed in github.

If 'ServiceURL' is set for a service in metadata, a link to that URL are
created in consentAdmin, to let users easy access the given service.
