[Murano] Floating IP cannot be assigned if instance joins an existing network but not the env's default

[Alexander Tivelkov]

If the Instance joins an existing network without joining an environment's default network, it may not be assigned a floating IP address.

This happens because fip assignment requires a so-called "primary network" which get automatically resolved as "either a default environment's network or a flat network is the former is not assigned".

If neither environment's default nor flat networks are assigned for the instance, but some custom networks are present, some of them should be chosen as "primary", however this does not happen.

Use Custom networks as primary if no others exist

Modify the logic of primary network detection, so if the instance does
not join environment's default of flat networks, but some custom
networks are passed, the first of them is used as a primary one.

This fixes the issue when the floating ip address could not be assigned
in case of custom networking configuration.
