chore: move process options to struct (#1109)

<!-- markdownlint-disable MD041 -->
#### What this PR does / why we need it

This is a follow up from
#1070 as @fabianburth
and I decided that it would probably be best to group process related
options under a specific struct to make it more explicit that they are
optional and not part of the normal resource description
