Add an option to support and enable this feature, as it is not clear, depending on the driver version, if this flag defaults to true or not.

not sure what this brings: we want to use this mode, it should not be disabled, and is the default in the version of arsenal where you add it...

[williamlardier]

@francoisferrand it is not clearly documented if the option is set to true by default, if the option is still useful, or not. The only hint is here: https://www.mongodb.com/docs/drivers/node/current/whats-new/#mongoclientoptions-interface

In some other places like here https://www.mongodb.com/docs/atlas/resilient-application/, they still use it.
So it won't hurt making sure this option is set to true when we explicitly want to have it.

The link you mention indicates it is not needed anymore (which is a hint for "should not be used" or "is useless"); and looking at the (official) documentation [1] it is not present anymore, since 5.0 at least...
