CDRIVER-2466 added a warning if crypto was not enabled while parsing a retryWrites URI option. When retryable writes was disabled by default, it was likely that the URI option would only be used to enable the feature; however, as CDRIVER-2961 will enable retryable writes by default it is more likely that some users might use the option to explicitly disable the feature.

It would be more correct for the URI parsing to only log a warning if crypto is disabled and retryWrites=true is parsed.
