VPN test environment

[dmarti]

We have the option of using 2 different VPN systems:

• SSTP

• L2TP/IPSec (These always seem to take longer to get setup but are secure and supported by nearly everyone.)

We need a compatible test VPN (as a Docker container?) for OpenWPM's own VPN to connect to.

One router that we have the option to VPN into: https://wiki.mikrotik.com/wiki/Manual:TOC )

Measure traffic to figure out how many instances we can run in parallel -- also if we need to add sleeps. -- want to keep below 1Gbps.

This can hopefully be done using https://cloud.google.com/vpc/docs/routes however it requires a lot more research and consideration
