Persist light client bootstrap (#5915)

* persist light client updates * update beacon chain to serve light client updates * resolve todos * cache best update * extend cache parts * is better light client update * resolve merge conflict * initial api changes * add lc update db column * fmt * added tests * add sim * Merge branch 'unstable' of https://github.com/sigp/lighthouse into persist-light-client-updates * fix some weird issues with the simulator * tests * Merge branch 'unstable' of https://github.com/sigp/lighthouse into persist-light-client-updates * test changes * merge conflict * testing * started work on ef tests and some code clean up * update tests * linting * noop pre altair, were still failing on electra though * allow for zeroed light client header * Merge branch 'unstable' of https://github.com/sigp/lighthouse into persist-light-client-updates * merge unstable * remove unwraps * remove unwraps * fetch bootstrap without always querying for state * storing bootstrap parts in db * mroe code cleanup * test * prune sync committee branches from dropped chains * Update light_client_update.rs * merge unstable * move functionality to helper methods * refactor is best update fn * refactor is best update fn * improve organization of light client server cache logic * fork diget calc, and only spawn as many blcoks as we need for the lc update test * resovle merge conflict * add electra bootstrap logic, add logic to cache current sync committee * add latest sync committe branch cache * fetch lc update from the cache if it exists * fmt * Fix beacon_chain tests * Add debug code to update ranking_order ef test * Fix compare code * merge conflicts * merge conflict * add better error messaging * resolve merge conflicts * remove lc update from basicsim * rename sync comittte variable and fix persist condition * refactor get_light_client_update logic * add better comments, return helpful error messages over http and rpc * pruning canonical non checkpoint slots * fix test * rerun test * update pruning logic, add tests * fix tests * fix imports * fmt * refactor db code * Refactor db method * Refactor db method * add additional comments * Merge branch 'unstable' of https://github.com/sigp/lighthouse into persist-light-client-bootstrap * fix merge * linting * merge conflict * prevent overflow * enable lc server for http api tests * fix tests * remove prints * remove warning * revert change
