[ML] Add ability to view and edit filter lists for use in detector rules

[peteharverson]

Filter lists are used in machine learning detector rules to supply the detector with domain knowledge that can improve the quality of the results. For example, a detector that performs a population analysis looking at bytes sent over IP addresses could benefit from a rule defining a list of IP addresses that the user knows to be 'safe'. Anomalous results for those IP addresses would then not be created.

Work has been done to redesign rules in elastic/elasticsearch#31110. This is a meta issue listing the features that need to be implemented in the UI to configure filter lists for use in the optional scope part of a rule, specifying a list of items as a filter on any of the 'partition', 'by' or 'over' field of the detector.

• Display all the configured filter lists under the Settings page
• Allow the filter list to be viewed showing
  • Filter ID
  • Description
  • List of items in the filter
  • Count of detectors using the filter
• Allow the user to create a new filter list
• Allow the user to edit an existing filter list
  • Add, edit or delete items
  • Edit description
• Allow the user to delete a filter list if it is not being used by an detectors
• Allow the user to search for items in the filter
• Check permissions before allowing user to create, edit or delete a filter

Prototype design for the page for viewing and editing a filter list:
