EXP-232.  Merge modeling in/outspec with flow API.

Update KijiInputSpec, KijiOutputSpec, KijiSingleColumnOutputSpec to more
closely match the argument lists for KijiInput and KijiOutput from
org.kiji.express.flow.

This change allows us to remove ExpressColumnRequest and
ExpressDataRequest.

This change depends on a pending change to the KijiExpress flow API that
absorbs the ExpressColumnFilter as a member of ColumnRequestInput.

As part of this change, move ExpressColumnFilter and the other Express
filters to org.kji.express.flow.

EXP-263.  Update Avro specs for KijiInput/OutputSpec.

Match API changes from EXP-232.

Avro spec, Avro conversion code matches the updated KijiInputSpec and
KijiOutputSpec (e.g., uses ColumnRequestInput/Output instead of
ExpressDataRequest).

Add support for serializing the schemaSpec members of ColumnRequestInput
and ColumnRequestOutput introduced in EXP-222.
