Single blob lookups (#4152)

* some blob reprocessing work

* remove ForceBlockLookup

* reorder enum match arms in sync manager

* a lot more reprocessing work

* impl logic for triggerng blob lookups along with block lookups

* deal with rpc blobs in groups per block in the da checker. don't cache missing blob ids in the da checker.

* make single block lookup generic

* more work

* add delayed processing logic and combine some requests

* start fixing some compile errors

* fix compilation in main block lookup mod

* much work

* get things compiling

* parent blob lookups

* fix compile

* revert red/stevie changes

* fix up sync manager delay message logic

* add peer usefulness enum

* should remove lookup refactor

* consolidate retry error handling

* improve peer scoring during certain failures in parent lookups

* improve retry code

* drop parent lookup if either req has a peer disconnect during download

* refactor single block processed method

* processing peer refactor

* smol bugfix

* fix some todos

* fix lints

* fix lints

* fix compile in lookup tests

* fix lints

* fix lints

* fix existing block lookup tests

* renamings

* fix after merge

* cargo fmt

* compilation fix in beacon chain tests

* fix

* refactor lookup tests to work with multiple forks and response types

* make tests into macros

* wrap availability check error

* fix compile after merge

* add random blobs

* start fixing up lookup verify error handling

* some bug fixes and the start of deneb only tests

* make tests work for all forks

* track information about peer source

* error refactoring

* improve peer scoring

* fix test compilation

* make sure blobs are sent for processing after stream termination, delete copied tests

* add some tests and fix a bug

* smol bugfixes and moar tests

* add tests and fix some things

* compile after merge

* lots of refactoring

* retry on invalid block/blob

* merge unknown parent messages before current slot lookup

* get tests compiling

* penalize blob peer on invalid blobs

* Check disk on in-memory cache miss

* Update beacon_node/beacon_chain/src/data_availability_checker/overflow_lru_cache.rs

* Update beacon_node/network/src/sync/network_context.rs

* fix bug in matching blocks and blobs in range sync

* pr feedback

* fix conflicts

* upgrade logs from warn to crit when we receive incorrect response in range

* synced_and_connected_within_tolerance -> should_search_for_block

* remove todo

* Fix Broken Overflow Tests

* fix merge conflicts

* checkpoint sync without alignment

* add import

* query for checkpoint state by slot rather than state root (teku doesn't serve by state root)

* get state first and query by most recent block root

* simplify delay logic

* rename unknown parent sync message variants

* rename parameter, block_slot -> slot

* add some docs to the lookup module

* use interval instead of sleep

* drop request if blocks and blobs requests both return `None` for `Id`

* clean up `find_single_lookup` logic

* add lookup source enum

* clean up `find_single_lookup` logic

* add docs to find_single_lookup_request

* move LookupSource our of param where unnecessary

* remove unnecessary todo

* query for block by `state.latest_block_header.slot`

* fix lint

* fix test

* fix test

* fix observed  blob sidecars test

* PR updates

* use optional params instead of a closure

* create lookup and trigger request in separate method calls

* remove `LookupSource`

* make sure duplicate lookups are not dropped
