Test Syncing with Another Fully Synced Service (#1594)
* clean up test

* adding test setup

* add chainstart check to sync querier

* goimports

* goimports

* backend cleanup

* adding getters

* lint

* moving to db

* gazelle

* adding more services setup

* adding more changes

* adding different test setups

* other merge issues

* imports

* fixing keys

* get intial sync able to be set up

* new changes and gazelle

* use simulated p2p

* everything finally works

* unexport fields

* revert changes from merge

* remove mock server

* add documentation

* gazelle

* add another node

* review comments

* fix tests
