72cfe1b4c3 feat: allow span filtering in service graph processor (#6453)
* added spanfilter to filter out spans

* return the error if the filters are not correctly formatted

* add filters to the userconfigurable overrides

* add core logic for drop items cache

* wired up everything

* some tweaks

* refactor

* fmt and manifest

* tighten names

* rename metric

* drop already buffered counterparts when a span is filter out

* add a new test and documentation

* Update docs/sources/tempo/operations/manage-advanced-systems/user-configurable-overrides.md

Co-authored-by: Suraj Nath <[email protected]>

* Update docs/sources/tempo/configuration/_index.md
