Mutation frequency support

• To be consistent with other IQuery services, version bumped up to 0.8.0

• Bumped jetty version to 9.4.45.v20220203

• Bumped jackson-databind to 2.9.10.8

• Added support for mutation frequency if caller includes geneAnnotationServices in query with
  URLs to service endpoints that provide mutation frequency. This includes addition of a mock mutation
  frequency endpoint

• When submitting query the resulting json now includes a webURL link that displays the
  results of that query in IQuery

• Fixed possible race conditions during processing of queries by adding synchronized wrappers

• Added logging of query genes and input sources. Also added logging of requests ip address and endpoint visited

Bug fix

• Fixed a bug where if a query had no results the source would be omitted from
  the returned JSON which did not adhere to the expected behavior of web UI. UD-1591
