refactor(ci): use docker instead of Konlet for GCP deployments in CI

[gustavovalverde]

Motivation

This is a workaround for an issue related to disk partitioning, caused by a GCP service called Konlet, while mounting the cached disks to the VM and then to the container.

This has been causing most integration tests to fail when a disk with cached state is needed.

Fixes #4114
Closes #4080
Closes #4090
Depends-On: #4266

Solution

• Do not run our tests directly by GCP services, instead manually create a container inside the VM with docker

** Drawbacks **

• We won't have the container logs available in GCP, but this is not as important as having the logs available in GitHub Actions, and we're not yet using GCP for reporting.

Review

Reviewer Checklist

• Code implements Specs and Designs
• Tests for Expected Behaviour
• Tests for Errors

Follow Up Work

Follow up with GCP support ticket to confirm if there's a fix or an unknown workaround which doesn't require us to stop using Konlet.

I've confirm we'll have to use this workaround. The solutions given by GCP's support (which fixed other issues) didn't fix this one.

This is a large PR, which I'm having trouble understanding and reviewing.

It looks like the diff contains:

• changes from previous PRs in this series
• bug fixes
• functional changes
• syntax and name cleanups

I'd really like to see:

• a list of changes in this PR
• how you've tested it
• test logs that show that we haven't accidentally skipped any tests

If it's not possible to test it until it is merged to main, can we just fix one workflow or disk first? Then we can fix the other workflows once we know the fix works.

@teor2345 I've removed everything that's not related to this PR

[gustavovalverde]

After merging

• fix(ci): create a full sync disk to add the cached state inside #4266

This is the most relevant PR to get lightwalletd CI working

[teor2345]

Alright, let's try this and see how it goes.
