[Feature]: setupExec and teardownExec

[xenoterracide]

🚀 Feature Proposal

I'd like a setupExec, setupExecAfterEnv and teardownExec that can run arbitrary commands added to the config parameters

Motivation

For integration testing servers may need to be started and stopped, this can be accomplished with setupFiles* currently, however it takes quite a bit of effort. In my case I spent half a day figuring out how to get a wait-for.sh replacement, and the ability to run a yarn command as well as write my setup files in typescript.

Example

instead of in the projects array

    {
      displayName: 'integration',
      testMatch: ['<rootDir>/**/test/integration/**/*.test.ts'],
      runner: 'jest-runner',
      transform: tsjPreset.transform,
      setupFilesAfterEnv: ['./jest/dist/serve.js', './jest/dist/wait-for.js'],
    },

    {
      displayName: 'integration',
      testMatch: ['<rootDir>/**/test/integration/**/*.test.ts'],
      runner: 'jest-runner',
      transform: tsjPreset.transform,
      setupExecAfterEnv: ['yarn serve', './wait-for.sh'],
    },

Pitch

I can only imagine setting up and tearing down servers is very common, this also helps IDE's run integration tests without developers remembering to start servers.
