FE: Add CI variable filter

Why are we doing this work

• users want to be able to add the appropriate CI variables for scan execution policies

Relevant links

• see epic

Implementation plan

• frontend create CI variable filter
  • conditionally show variables in dropdown based on scan type selected (see lists below)
  • use a GlCollapsibleListbox and the action Use a custom key changes the dropdown to an input box
