Meraki module utility - get_net() downloads networks if data isn't provided (#41423)

* Enable get_net() to download nets if data isn't provided

- Currently, get_net() requires data to be passed to it
- PR enables get_net() to download all networks if data isn't passed
- Slightly simpler code
- Best practice is to download nets early in execution

* Apply fixes related to get_net()

* Removed extra code from the rebase
