Add new feature for custom workspace network CIDR

[aledbf]

Description

The default workspace network cell uses a private range that can conflict with some pre-existing network in the VPC that creates a network routing error (no route to host) when we try to reach any IP address of the such subnet.
For this scenario, we introduce a new ws-daemon parameter that allows us to set a different subnet. If the parameter is not present, we use the default value we use.

fixes WKS-50

How to test

• Use the default configuration
  • Verify workspaces run
  • Check the IP addresses in the workspace. The value should be 10.0.5.2/30
• Change the installer configuration to set a different subnet
  • Verify workspaces run
  • Check the IP addresses in the workspace. The value should match the subnet, and the workspace should have the second IP address in the range.
