Parse domain_name header

The 'name' headers (eg. X-User-Name) and the 'id' headers
(eg. X-User-Id) are handled almost consistently, but for only domain
header we read only id.

Add the parse marker to make sure that the X-Domain-Name header is
loaded to RequestContext, so that both name and id are present for
domain scoped access.
