Create locally Linux VM to be used as self-hosted agent for AzureDevOps pipelines

1. Provision VM (here image: CentOS7)
2. Install initial packages (Java11 OpenJDK, Maven, GIT...)

Configure agent and add token for AzureDevOps connection (one-time action)

1. Create directory for agent installation mkdir myagent && cd myagent
2. Download and extract installation files
   wget https://vstsagentpackage.azureedge.net/agent/2.211.1/vsts-agent-linux-x64-2.211.1.tar.gz
tar zxvf vsts-agent-linux-x64-2.211.1.tar.gz
3. Run config.sh to install and configure agent. You need to have agent pool already created in AzureDevOps. On this step you add Azure DevOps token.
4. sudo ./svc.sh install vagrant (by each next VM start agent is started and connected to AzureDevOps automatically).
5. sudo ./svc.sh start and check if running sudo ./svc.sh status.
6. Check Azure DevOps portal if your agent is available and run sample pipeline defining usage of this agent.
