feat: use fastcache (#164)

* feat: use fastcache for interblock cache

* feat: add prometheus metric

* feat: add more cache metric; bytes size, entry count

* chore: param caching

* feat: use fastcache as iavl nodedb cache

* chore: remove debugging code; fix lint error

* chore: fix lint error

* chore: raise codecov

* chore: raise codecov, modify metric description

* chore: raise codecov

* chore: disable Pseudo-Comparison of codecov

* chore: trying codecov to succeed

* chore: release threashold of coverage to update base report

* chore: trying codecov to succeed

* chore: base coverage is too low. lower target

* chore: enable codecov app, modules, client

* chore: enable codecov patch

* chore: use telemetry instead of prometheus
