GraphRandomErrorPlugin throws on HEAD, OPTIONS and other methods #1955

Description

_methodStatusCode only has entries for GET, POST, PUT, PATCH and DELETE. For any other method (HEAD, OPTIONS, …), the lookup _methodStatusCode[method] throws KeyNotFoundException.

  	HttpStatusCode.InternalServerError,
  	HttpStatusCode.BadGateway,
  	HttpStatusCode.ServiceUnavailable,

  Line 214 in 43b3724

  var methodStatusCodes = _methodStatusCode[e.ProxySession.Request.Method];

• dev-proxy/DevProxy.Plugins/Behavior/GraphRandomErrorPlugin.cs

  Line 238 in 43b3724

  var methodStatusCodes = _methodStatusCode[request.Method];

Expected behavior

Requests with other methods either pass through or get a generic error, without an exception.
