refactor to remove warnings especially with orphan instances (#1163)
* remove phase one/two distinction and hdbquery typeclass

* move extensions to default-extensions

* switch to LazyTx which only acquires a connection if needed

* move defns from TH module into Ops module

* remove tojson orphan instance for http exception

* remove orphan instance for dmlp1
