Jędrzej Stuczyński d8c84cc4d6 feat: key rotation (#5777)
* wip

* wip: wrap node's sphinx key with a manager

* wip: choosing correct key for packet processing

* further propagation of key rotation information

* attaching key rotation information to reply surbs

* added basic key rotation information to mixnet contract

* wip: introducing cached queries for key rotation info from nym api

* unified nym-api contract cache refreshing

* finish packet decoding

* multi api client + retrieving rotation id

* rotating sphinx key files

* logic for migrating config file

* wip: putting new sphinx keys to self described endpoints

* processing loop of KeyRotationController

* fixed sphinx key loading

* rotating bloomfilters

* wired up KeyRotationController

* flushing bloomfilters to disk and loading

* most of nym-node changes

* post rebase fixes

* fixes due to backwards compatible hostkeys

* split http state.rs file

* dont use deprecated fields

* fixed backwards compatible deserialisation of host information

* split up node describe cache

* added a dedicated CacheRefresher listener to perform full refresh outside the set interval

* controlling announced sphinx keys within nym-api

* retrieving rotation id when pulling topology

* split nym-nodes http handlers

* v2 nym-api endpoints to retrieve nodes with additional metadata information

* bug fixes...

* additional bugfixes and guards against stuck epoch

* testnet manager: set first nym-api as the rewarder

* fixed host information deserialisation

* fixed panic during first key rotation

* post rebase fixes

* clippy

* more guards against stuck epochs

* added helper method to reset node's sphinx key

* instantiate mixnet contract with custom key rotation validity

* additional bugfixes and debugging nym-api deadlock

* passing shutdown to nym apis client

* remove dead test

* post rebasing fixes

* missing MixnetQueryClient variants

* remove usage of deprecated methods in sdk example

* fix: incorrect method signature

* post rebasing fixes

* attempt to retrieve key rotation id before doing any config migration work

* ignore tests relying on networking behaviour

* allow networking failures in certain tests
