Explorer crate (#3350)

* workspace: add explorer crate

- the logging setup is copy-pasted from jormungandr

* jormungandr: remove explorer module

* jormungandr: remove async-graphql dep from jormungandr

* jormungandr-lib: remove explorer import

* tests: remove explorer

* tests: regen explorer schema without treasury for now

having integration tests with the explorer and jormungandr will always
be good anyway, so having a way of launching an explorer in integration
tests for the purposes of testing the explorer is something that we
probably want. This is a first approximation towards that.

* tests: add explorer env var

* tests: remove explorer where necessary

* remove whitespace from autgenerated graphql schema

in order to please the editorconfig check

* port Transaction total_count fix

* add(port) ConfigParams to GraphQL

* remove enum name from variants

* reorganize imports

* explorer crate: add warp filter like in jormungandr

* circle: build explorer before running tests

* add(port) MintToken

* fix tests: use rest for current time instead of explorer

* return a Result in set_tip

this makes the code a bit more self-documenting than with a boolean,
even if the error value is not actually used here.

* remove unused Result alias

* build explorer in actions test pipeline too

* handly tally type at an earlier point

because otherwise the function will panic for public tally, as there is
no decrypted tally

* log listen address when cors is not enabled

* collect tally result instead of looping

* remove line added by mistake

* fix PersistentSequence::is_empty

it was returning the opposite value

* remove unused files

* impl From instead of TryFrom

* use Certificate::from instead of try_from

* fix tests: explorer is not a node setting anymore

* add retry when querying the explorer

to account for slow IO, or performance issues when running the test

* move explorer process spawn to JormungandrProcess

this allows using it in other tests, like in
`retire_stake_pool_explorer` and other integration tests

* remove unnecessary thread::sleep in test

* handle evm config param

by just panicking, proper suppport can be done later

* fix compilation issues

* port EvmConfig code from jormungandr

* add changelog entry

* update Cargo.lock

* port/update config_param.rs

* refactor subscriber init

* test: send explorer logs to stdout

* explorer sanity test: reduce attemps to 20
