actually I think the localnet check needs to be migrated to GH actions

[alessio]

@fedekunze is right, we should add something like the following:

  liveness-test:
    runs-on: ubuntu-latest
    timeout-minutes: 10
    steps:
      - uses: actions/checkout@v2
      - uses: actions/[email protected]
        with:
          go-version: 1.15
      - uses: technote-space/get-diff-action@v4
        id: git_diff
        with:
          PATTERNS: |
            **/**.go
            go.mod
            go.sum
      - name: start localnet
        run: |
          make clean build-simd-linux localnet-start
        if: env.GIT_DIFF
      - name: test liveness
        run: |
          ./contrib/localnet_liveness.sh 100 5 50 localhost
        if: env.GIT_DIFF

I invoke our Github Actions Overlord @marbar3778 🙏

should this be commented?

[shahankhatch]

No, it shouldnt be. I had commented it just to trigger the action and test. Since it appears it's fine I will uncomment, commit, and merge the PR.
Thanks @marbar3778
