Validation of Server is incorrect

[3dquattro]

Description

There is incorrect validation for server details when it is requested on early stage - when it is starting, when cloud returns it without properly configured networks.

Steps to reproduce

1. Run server on eu01 region (looks like it is heavy loaded now)
2. Request server details like this when it is being created:

server = client.get_server(
                    self.project_id, self.region, server_id, details=True)

Actual behavior

Error like this:

ValidationError: resources.vm3-clone3: 2 validation errors for ServerNetwork
mac
Value error, must validate the regular expression /^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$/ [type=value_error, input_value='', input_type=str]

networkName
Value error, must validate the regular expression /^[A-Za-z0-9]+([ \/._-]*[A-Za-z0-9]+)*$/ [type=value_error, input_value='', input_type=str]
For further information visit https://errors.pydantic.dev/2.13/v/value_error

Expected behavior

Validation should pass, because it is correct response from cloud API
