(fix): reduce executor logs (#11169)

* remove driver logs from executor

These logs congest the executor runtime logs making it difficult for the
user to differentiate between logs. The driver logs are unnecessary here
and can be removed to reduce this clutter.

* remove duplicate emissary call in executor

As per the initial inline dev comment, argo podspecpatch did not add the
emissary call, and had to be manualy added. This was fixed a couple of
argo versions back. However, as a result executor pod makes double calls
to the executor, which as a consequence also results in superflous logs.

This change removes the additional call to emissary to resolve this.
