[chore][PLAT-1058] Add support for extraContainers to code-executor deployment

[jthemphill]

Test to make sure that existing templates don't completely change:

# See generated templates without the change
git checkout main
mkdir -p /tmp/before
for f in charts/retool/ci/*.yaml; do
  name=$(basename "$f" .yaml)
  helm template charts/retool -f "$f" > /tmp/before/$name.yaml 2>&1
done

# See generated templates with the change
git checkout jhemphill/helm-extra-sidecar
mkdir -p /tmp/after
for f in charts/retool/ci/*.yaml; do
  name=$(basename "$f" .yaml)
  helm template charts/retool -f "$f" > /tmp/after/$name.yaml 2>&1
done

# Diff to make sure existing templates are unchanged
diff -r /tmp/before /tmp/after

Result of diff
