* Add near-miss diagnostics and request count/unmatched admin endpoints (#171)
Add IWireMockServer.FindUnmatchedLogEntries, FindNearMisses and
FindNearMissesForUnmatchedRequests, which rank the mappings that
partially match a request by score.
Expose them through the admin API (POST requests/count,
GET requests/unmatched, GET requests/unmatched/near-misses and
GET requests/{guid}/near-misses), the RestClient and the OpenAPI document.
* Make scenario delay tests independent of server warm-up time
The two *_StateTransitions_BeforeDelayCompletes tests waited a fixed
100 ms for the scenario state to change, which fails on a cold server.
Poll server.Scenarios until the expected state is reached instead.
