This adds the for-internal-use-only src batch exec command that will be used by server-side batch changes to execute a batch spec in specific workspaces on different machines, concurrently.
Note: the vast majority of the added code you see here is copy&pasted from batch_common.go. I really don't want to add more conditionals to the huge function in there though, so I created a new one. Yes, there's duplication, but it's so much easier to understand and to maintain. And we'll likely make a lot of changes to this new function here anyway, so effort to generalize and DRY this code will probably be wasted.
Given the following input file, input.json
{
"rawSpec": "\nname: text-only-output-4\ndescription: Just a test campaign spec to test text only output\n\non:\n - repository: github.com/sourcegraph/automation-testing\n # - repository: github.com/sourcegraph-testing/mkcert\n # - repository: github.com/sourcegraph-testing/tidb\n # - repository: github.com/sourcegraph-testing/titan\n # - repository: github.com/sourcegraph-testing/etcd\n # - repository: github.com/sourcegraph-testing/tiny-go-test-repository\n\nsteps:\n - run: |\n echo \"this is step 1\" >> README.txt\n echo \"this is step 1\"\n echo \"this is step 1\" 1>&2\n container: alpine:3\n - run: |\n echo \"this is step 2\" >> README.md\n echo \"this is step 2\"\n echo \"this is step 2\" 1>&2\n container: alpine:3\n - run: |\n echo \"this is step 3\" >> README.md\n echo \"this is step 3\"\n echo \"this is step 3\" 1>&2\n container: alpine:3\n outputs:\n myOutput:\n value: \"my-output.txt\"\n - run: |\n echo \"this is step 4\" >> README.md\n cat README.md\n echo \"previous_step.modified_files=${{ previous_step.modified_files }}\" >> README.md\n ls -lrt\n container: alpine:3\n - run: echo \"this is step 5\" >> ${{ outputs.myOutput }}\n container: alpine:3\n\nchangesetTemplate:\n title: Testing step caching\n body: Testing step caching\n branch: thorsten/text-only-output-2\n published: true\n commit:\n message: Caching testing\n",

}we can use src batch exec to execute the workspaces.steps (not the steps in the included raw batch spec!!) in the given workspaces:
src batch exec -f input.json
