Multi-select in network/connection modal

[0x1a8510f2]

Is your feature request related to a problem? Please describe.
When adding hosts to networks or adding connections, one might want to add multiple at a time. This is currently not possible through the web UI (and I assume the API too because the CLI also allows adding one connection/network per command, but that makes sense in this case) but would make the process of configuring networks much quicker and simpler.

Describe the solution you'd like
The API may need to be modified to accept multiple connection/network changes at a time if this is not yet the case, for the sake of efficiency. Otherwise, converting the radio buttons in the modal to checkboxes ui-wise would solve the problem nicely. A "select all" option would also be useful.

Describe alternatives you've considered

Thank you for your suggestion. It does make a lot of sense. Will keep it in mind for future releases.
