Migrate to Gitlab

[esteve]

Steps:

• @daggarwa merges or closes open PRs: https://github.com/ApexAI/performance_test/pulls
• @esteve Create repository in https://gitlab.com/ApexAI. Currently it's a mirror of this repository, ask @jpsamper2009
• Update CI to use Gitlab, we're currently using Azure Pipelines in this repository.
  • Idea: revert Removed Gitlab CI #61
  • PR in Replace Azure Pipelines with Gitlab CI #96
• migrates the issues
  • @esteve: Gitlab fails to import the GitHub project, it could be because I don't have enough permissions to create repositories in the ApexAI GitLab organization
• keep this repository empty and add a note (same as what we did in Autoware.AI)
• Hand maintainership over to @daggarwa
