Version attribute in SCIM Metadata response does not follow RFC

[nwoolls]

Currently, the version attribute returned by the SCIM server in the meta section of a resource is a number. The RFC for SCIM 2 indicates this should be an ETag. Most implementations I've worked with (and indeed all of the RFC examples) have this attribute as a string, so our parsing logic falls down when this SCIM server returns a number.

See: https://datatracker.ietf.org/doc/html/rfc7643#section-3.1

Hello,

The issue has been fixed in the Release503 branch. The version property of a representation is now returned as a string.

By default, the version is an integer that increments each time a modification is made to the representation. However, you can define your own versioning logic by implementing the following interface:

public interface IRepresentationVersionBuilder
{
    string Build(SCIMRepresentation representation);
}

public class CustomRepresentationVersionBuilder : IRepresentationVersionBuilder
{
    public string Build(SCIMRepresentation representation)
    {
        return Guid.NewGuid().ToString()
    }
}
