Allow passing MongoDB Native options when calling connect

[jloveridge]

Sometimes it is useful to pass additional options to the driver when connecting. Specifically we needed to be able to pass options that affect the SSL connection since require certificate authentication signed by our CA. While it is possible to create a DB connection externally and pass that instead of the other options we liked the simplicity of passing the options directly.

thanks for the contribution @jloveridge 🤘
I think testing for certificates is a bit excessive, you can just verify, that driver options passed properly, so it can be part of regular test cycle.
