PROV definitions as OAP Part 5

[fmigneault]

Summary

• Align with Part5 Provenance opengeospatial/ogcapi-processes#605
• Align with Part 4/5 updates (job inputs->definition) and adjusted conformance URIs

---

Changes:

• Align GET /jobs/{jobId}/definition (replaces GET /jobs/{jobId}/inputs) with the
  most recent OGC API - Processes - Part 4: Job Management specification,
  which includes the entity URI of the appropriate Process definition at the root of the Job/Workflow.
• Support application/provenance+json and application/provenance+xml for corresponding provenance media-types
  (fixes Support application/provenance+xml for PROV-XML #987).
• Update and add new /conformance references of Job definition and provenance requirements and recommendations.
• Update Job provenance error responses with standard type URIs.

Fixes:

• Fix Job provenance to provide Weaver and weaver-worker references as SoftwareAgent rather than Person
  (relates to PROV: improve source code references #965).
• Fix URL schema validation error on Job links when they include a result with a ?f={mediaType} query parameter.
  The URL pattern did not correctly provide the anchor and query parameter components. Also, if the media-type had some
  special characters (e.g., a space between its parameters), it would fail due to the missing URL encoding. Finally, the
  actual URL returned was missing the /results/ portion of the /jobs/{jobId}/results/{outputId} endpoint.
• Fix missing unquote operation to handle URL encoding for ?f={mediaType} on result endpoint for above change.
