* [OT] use `new` builtin for visual clarity
`new(ExternalTokenHelper)` is a lot easier to parse than
`(*ExternalTokenHelper)(nil)`
* add `Args` field to `ExternalTokenHelper`
This will be used to store any extra command arguments and allows
`BinaryPath` to hold *just* the binary path.
* remove shell invocation
Since `BinPath` no longer has to hold any additional arguments we can
execute the command directly without inoking the shell first.
* update `testExternalTokenHelper` to make use of the new `Args` field
* updated `ExternalTokenHelper` documentation
* Add changelog entry for token_helper without shell
Currently using 0.txt until we have a PR id.
* Rename 0.txt to 29653.txt
We got a PR ID, so fix the changelog file
