org.apache.calcite.adapter.enumerable.EnumerableInterpretable#getBindable.

Cherry-pick from 
[https://github.com/apache/calcite/pull/950|https://github.com/apache/calcite/pull/950,],
 Calcite 1.19 uses Guava cache on Bindable instances.

Similar to {{calcite.bindable.cache.maxSize}} and 
{{{}calcite.bindable.cache.concurrencyLevel{}}}, two KYLIN configs are added as 
follows:

 
{code:java}
# Cache max size, default value is 10
kylin.query.calcite.bindable.cache.maxSize
# controll the concurrency level of cache, default value is 5
kylin.query.calcite.bindable.cache.concurrencyLevel{code}
