Update azure-mgmt-network package version

[Balashivaram]

Description

Updated the "azure-mgmt-network" package version from 19.3.0 to 27.0.0. The new package will have support to update the package with defaultOutboundAccess parameter.

As part of SFI changes, we can't either create private subnet or update private subnet to non private subnet. During the resource creation we are able to create subnet as private via enable_vm_nat parameter, but when we are calling this function create_route_table, we are dropping the defaultOutboundAccess parameter because the azure-mgmt-network package is dropping it. Updating the package will help us update the subnet with defaultOutboundAccess parameter

Related Issue

Before doing the above fix we were facing this issue, where defaultOutBoundAccess parameter is being dropped during this function call create_route_table. With SFI policies, when these parameters are not added the tests will fail with error

Note: The above error will be seen only if customer enforces that subnet should not be private in their subscription
After updating the package this parameter getting dropped will be resolved
