Connection strings with several hosts throw ERR_INVALID_URL error

[sigalor]

Steps to reproduce

Consider this connection string:

mongodb://root:xxxxx@db-host-0-service.default.svc.cluster.local:27017,db-host-0-service.default.svc.cluster.local:27017/my-database?authSource=admin&replicaSet=rs

It contains several hosts, separated by commas, which is of course allowed according to MongoDB's Connection String URI Format. Yet, due to commit 1d8a84b, where the library tries to parse this connection string via the new URL(...) constructor, initializing fails.

Current Behavior

When supplying such a connection string with multiple hosts, an error is thrown: TypeError [ERR_INVALID_URL]: Invalid URL: ..., because the URL constructor cannot handle several hosts separated by commas in one URL.

Expected Behavior

No error is thrown.
