Description

RelBuilder creation fails with error 'No suitable driver found for jdbc:calcite:'. We should not need to initialize a "jdbc:calcite" driver to make a RelBuilder.

We just tracked down a nasty issue with Calcite being shaded as a dependency in our code that could cause a stack like
 

No suitable driver found for jdbc:calcite: 
org/apache/calcite/tools/Frameworks.java:184:in withPrepare 
org/apache/calcite/tools/RelBuilder.java:225:in create

when calling RelBuilder.create.

Our fault ultimately, but Julian Hyde pointed out that Calcite really shouldn't be trying to make a JDBC connection here.
