[azure provider] ability to add azure subnet configuration

[Peter Jose De Sousa]

Hi,

When creating juju subnets the azure provider creates two resources with regards to networking: the vNet and a subnet within that vNet. There are requirements where this subnet and vNet names are required to be changed.

Much like the resource group change, this could take the form of a configuration or existing subnet name.

I would say letting juju creating this should take precident, in keeping with the juju paradigm and keeping the generic case supported.

Cheers!

Building on top of this, we are now dealing with a case there there is a central resource group (Spoke network) with vNets already deployed.

The vNets in this spoke resource group would then be used by the juju VMs (specified in a model configuration).

This is now handled by the model config item "network".
"network" can point to a resourcegroup/virtualnetwork
Subnets in that specified vnet will be used.

The other item is placement, eg

juju deploy mysql --to subnet=mysubnet

juju bootstrap azure --no-default-model --config network=myrg/myvnet --to subnet=mysubnet

And there's also spaces support

juju subnets
juju spaces
juju add-space
juju deploy --constraints="spaces=foo"
