Execute find and count queries in parallel for paginated requests

[winrono]

When find request is executed with pagination actual find and count requests are executed sequentially.

Lines 32 to 41 in 7f13742

	const results = await this._collection.find(query, options);
	if (!hasPaging) {
	return {
	results,
	};
	}
	const countOptions = {};
	if (options.session) countOptions.session = options.session;
	const count = await this._collection.count(query, countOptions);

Instead this could be performed in parallel noticeably improving performance for long-running DB requests
