Enable act tool for running CI jobs locally

[electrocucaracha]

Problem

act tool allows to execute GitHub actions locally. Actions like upload-artifact and cache use third-party services configured defined through ACTIONS_RUNTIME_URL, ACTIONS_RUNTIME_TOKEN and ACTIONS_CACHE_URL environment variables, this dependency limits the execution of act tool.

Change overview

This change allows the execution of act tool locally for development and validation of GitHub jobs.

It also upgrade the upload-artifact GH action version to v2.

Testing

To run this locally it's necessary to install act and its dependencies described here. Once it's installed, CI jobs can be tested executing the following command:

$ act

The previous command will execute all jobs currently defined, resulting in downloading ~55 GB and consuming + 210 GB in HDD (/var/lib/docker) therefore, it's highly recommended to select the jobs to test.

$ act --list
