Enable regex search (#4566)

* Adds custom search filter to allow 'regex' searching of results

* Specify if "shell" can access database for certain commands

* Bug fix for settings API

- Do not allow cache on detail endpoints
- Was causing strange error conditions with missing or duplicate PK values

* Adds user setting to control regex search

* Enable regex for search queries

- bootstrap tables
- search preview

* Pass search options through bettererer

* Refactor API endpoints to use new filter approach

* Bump API version

* Add "whole word" search

- Closes https://github.com/inventree/InvenTree/issues/4510

* Handle case where existing fields are empty

* pop > get
