Performance / locking fixes/enhancements (#65)

* Use a temp table rather than (slow) json concatenation in search function
* Reduce locks when creating constraints by using "NOT VALID"
* Add logic to remove any cached searches that use data from updated partitions on ingest (Fixes Update where_stats after ingest of new data #62 )
* Add validate_constraints function to validate any constraints constructed with NOT VALID flag
* Fixes issue with docker image startup. Use pypgstac migrate for initializing docker database (Fixes cannot start database service built with pgstac:v0.3.5  #59 )
