exec: Allow running commands from mounted host volumes
```
exec: allow running commands from host volume (#14851) The exec driver and other drivers derived from the shared executor check the path of the command before handing off to libcontainer to ensure that the command doesn't escape the sandbox. But we don't check any host volume mounts, which should be safe to use as a source for executables if we're letting the user mount them to the container in the first place. Check the mount config to verify the executable lives in the mount's host path, but then return an absolute path within the mount's task path so that we can hand that off to libcontainer to run. Includes a good bit of refactoring here because the anchoring of the final task path has different code paths for inside the task dir vs inside a mount. But I've fleshed out the test coverage of this a good bit to ensure we haven't created any regressions in the process. 2022-11-11 14:51:15 +00:00			```release-note:improvement
