EXP-85. packAvro now expects to pack Scala types, not Java types.

The method packAvro in KijiPipe is used to pack multiple Scalding
tuple fields into one AvroRecord. To do this, the values in the tuple
fields must be converted to instances of AvroValue (really AvroValue's
ancestors). Before this commit, KijiPipe used AvroUtil#wrapGenericAvro
to perform this conversion. This is incorrect, however, as
AvroUtil#wrapGenericAvro expects Java types as input, but the tuple
field values to be packed should be Scala types. This commit changes
packAvro to use AvroUtil#scalaToGenericAvro instead, which expects
Scala types to convert to AvroValues.

EXP-90. Proper configuration for jobs launched through schema-shell.

This commit modifies the execution of the model lifecycle through the
modeling schema shell model so that express library jars are shipped
with launched jobs. This is accomplished by setting a JVM property
containing a list of library jars through the express script, and then
reading that property when launching a job. Additionally,
configuration properties are set to disable schema validation for the
time being.

This commit also modifies things so that users can specify additional
library jars to ship with jobs not as URIs, but with absolute or
relative paths to the local file system.

This commit modifies the express script so that any left-justified

reflected in the configurations of jobs launched.
