CSUB-366: Deploy on demand self-hosted runners

[atodorov]

Description of proposed changes:

Practical tips for PR review & merge:

• All GitHub Actions report PASS
• Newly added code/functions have unit tests
  • Coverage tools report all newly added lines as covered
  • The positive scenario is exercised
  • Negative scenarios are exercised, e.g. assert on all possible errors
  • Assert on events triggered if applicable
  • Assert on changes made to storage if applicable
• Modified behavior/functions - try to make sure above test items are covered
• Integration tests are added if applicable/needed

For https://github.com/gluwa/creditcoin/actions/runs/3847172342/jobs/6553565221

1. A new VM has been provisioned - github-runner-3847172342.westus3.cloudapp.azure.com
2. A new self-hosted runner is registered with GitHub - github-runner-3847172342
3. The hardware-benchmarks job is executed on the freshly provisioned runner:

Current runner version: '2.300.2'
Runner name: 'github-runner-3847172342'
Runner group name: 'Default'
Machine name: 'github-runner-3847172342'

4. After job execution is done the self-hosted runner is removed from GitHub (runners are registered as ephemeral and are removed either after 1 job is executed on them or after 24 hrs of inactivity)
5. The VM github-runner-3847172342.westus3.cloudapp.azure.com is removed in the last job of the workflow.
