+ * Creates a new Server instance
+ * @class
+ * @deprecated
+ * @param {string} host The host for the server, can be either an IP4, IP6 or domain socket style host.
+ * @param {number} [port] The server port if IP4.
+ * @param {object} [options] Optional settings.
+ * @param {number} [options.poolSize=5] Number of connections in the connection pool for each server instance, set to 5 as default for legacy reasons.
+ * @param {boolean} [options.ssl=false] Use ssl connection (needs to have a mongod server with ssl support)
+ * @param {boolean} [options.sslValidate=false] Validate mongod server certificate against ca (needs to have a mongod server with ssl support, 2.4 or higher)
+ * @param {boolean|function} [options.checkServerIdentity=true] Ensure we check server identify during SSL, set to false to disable checking. Only works for Node 0.12.x or higher. You can pass in a boolean or your own checkServerIdentity override function.
+ * @param {array} [options.sslCA] Array of valid certificates either as Buffers or Strings (needs to have a mongod server with ssl support, 2.4 or higher)
+ * @param {array} [options.sslCRL] Array of revocation certificates either as Buffers or Strings (needs to have a mongod server with ssl support, 2.4 or higher)
+ * @param {(Buffer|string)} [options.sslCert] String or buffer containing the certificate we wish to present (needs to have a mongod server with ssl support, 2.4 or higher)
+ * @param {string} [options.ciphers] Passed directly through to tls.createSecureContext. See https://nodejs.org/dist/latest-v9.x/docs/api/tls.html#tls_tls_createsecurecontext_options for more info.
+ * @param {string} [options.ecdhCurve] Passed directly through to tls.createSecureContext. See https://nodejs.org/dist/latest-v9.x/docs/api/tls.html#tls_tls_createsecurecontext_options for more info.

+ * @param {(Buffer|string)} [options.sslPass] String or buffer containing the certificate password (needs to have a mongod server with ssl support, 2.4 or higher)
+ * @param {string} [options.servername] String containing the server name requested via TLS SNI.
+ * @param {object} [options.socketOptions] Socket options
+ * @param {boolean} [options.socketOptions.autoReconnect=true] Reconnect on error.
+ * @param {boolean} [options.socketOptions.noDelay=true] TCP Socket NoDelay option.
+ * @param {boolean} [options.socketOptions.keepAlive=true] TCP Connection keep alive enabled
+ * @param {number} [options.socketOptions.keepAliveInitialDelay=120000] The number of milliseconds to wait before initiating keepAlive on the TCP socket
+ * @param {number} [options.socketOptions.connectTimeoutMS=10000] How long to wait for a connection to be established before timing out
+ * @param {number} [options.socketOptions.socketTimeoutMS=0] How long a send or receive on a socket can take before timing out
+ * @param {number} [options.reconnectTries=30] Server attempt to reconnect #times
+ * @param {number} [options.reconnectInterval=1000] Server will wait # milliseconds between retries
+ * @param {boolean} [options.monitoring=true] Triggers the server instance to call ismaster
+ * @param {number} [options.haInterval=10000] The interval of calling ismaster when monitoring is enabled.
+ * @param {boolean} [options.domainsEnabled=false] Enable the wrapping of the callback in the current domain, disabled by default to avoid perf hit.
+ * @param {boolean} [options.monitorCommands=false] Enable command monitoring for this topology
