Create Default Log Options for Search

As a convenience for request and response logging we should compile a list of log-safe headers and query parameters. These lists should be used to built a default HttpLogOptions that could be retrieved through a static getter if the user wants to mutate the default log options.

@tg-msft @bryevdv @xirzec @heaths as this will be applicable to other languages as well.

I’d also suggest $select as an allowed query parameter.

We’re having internal discussions around whether field names are considered “sensitive data” that might need to stay in the region of the customer’s search service, so logging $select by default might be problematic for the same reason as $filter would be, at least for the query APIs (its usage for the various List<Resource> APIs is innocuous).
