Store shard config for peers and choose sync peers accordingly. (#77)

Browse Source 
* Implement Pruner.

* Put pruner in a crate.

* Fix clippy.

* Add rpc zgs_getShardConfig.

* Fix.

* Increase wait time.

* Add pruner_test and use max_num_chunks instead of size_limit.

* Store shard config for peers and choose sync peers accordingly.

* Add test and fix sync.

* Fix clippy and test.

* Fix some ut.

* Add AnnounceShardConfig gossip and fix tests.

* Add sharded tx finalize check in LogManager.

* Try,

* Rename.

* Longer timeout for mine_test.

* Save test logs.
