Subject: [PATCH] metadata: fix profile to be string, not dict

Per the FHIR spec, it is defined as a canonical URL (string):
https://www.hl7.org/fhir/capabilitystatement.html

And in fhirclient, it is validated as a string. The current
dictionary definition makes it impossible to use fhirclient to
inspect server metadata.

And removed non-spec parameter acceptUnknown
