* node/pkg/terra: remove setEvents
The guardian set should only be authoritative from ethereum, so having
this code in the terra watcher is unnecessary. Getting this information
on injective requires a few more hoops to jump through but it is never
used. It is easier to maintain less code, so remove it.
* node/cmd/guardiand: remove setEvents from cosmwasm
This removes the set events from:
* terra 2
* injective
* terra classic
* node/pkg/terra: don't query guardianset from cosmwasm
* node/pkg/terra: support injective
* node/pkg/terra: update queryLatency metric
To show the query latency of fetching the latest block height from rpc
