New GitHub actions based CI does not provide Vivado license

[hansfbaier]

This pull request runs successfully on my local machine,
but fails in the CI, because the added part is not available in the WebPack edition:
#1908

@acomodi / @kgugala - Can you take a look?

[acomodi]

@mithro One necessary step to solve this will most probably be the addition of the tunnel key as a GH secret, so that we can access the license server. We do not have access to the $KOKORO_KEYSTORE_DIR though, and I am not quite sure where to get it. I see it is currently fetched before running the kokoro action: https://github.com/f4pga/prjxray/blob/master/.github/kokoro/continuous-db-kintex7.cfg#L46-L53

[mithro]

@acomodi - We can set this up temporarily, but we should set it up so that the GitHub Runners on GCP can login to the tunnel server without needing a SSH key. I think there is some documentation at https://cloud.google.com/compute/docs/tutorials/service-account-ssh ?

[mithro]

I have created the LICENSE_TUNNEL_KEY_DATA GitHub secret. The contents of this file should be dumped into the LICENSE_TUNNEL_KEY file.

Testing in the branch at https://github.com/f4pga/prjxray/tree/xilinx

[mithro]

@acomodi - It seems like the commands are being run as root?

[mithro]

I think what is needed is now shown in https://github.com/f4pga/prjxray/pull/1918/files

We just need to make sure that the Google Cloud Platform which has the runners can connect to the Xilinx license server machine.

[mithro]

Okay, I think we have xilinx-license servers setup in the correct GCP projects, however I'm unclear how to the runners can access the GCP private network (10.138.0.0).
