User cannot create an admin network without knowing the physical network name

[Kahou Lei]

Currently user cannot create an admin network without knowing the physical network name.

It will be more convenient if the physical network field is a choice field such that user can choose the name from the list.

Steps to reproduce:

1. Go to Admin -> Network
2. Click create network
3. You will notice that the physical network field is a text field

    Provide available physical networks on create network modal

    Added setting physical_networks to provide users list of
    available physical networks to choose from on the
    admin create network modal.

    Default to an empty list and the physical network field is
    a regular input field where users can type in the name
    of the physical network to be used.

    If it's set to a list of physical network names, the
    physical network field is a dropdown menu where users can
    choose a physical network to use.
