ext-data-source only needs a small subset of the thrift structures, so this
separates the dependencies between files so that just the necessary structs
are generated for ext-data-source. Afterwards, we can remove extra maven
dependencies which were using environment variables to get versions. While the
environment variables work when building the pom, they are not propagated to
dependencies so building fe/pom.xml ended up producing lots of warnings which
are now gone.

A few changes to the external data source thrift types:
* Change RowBatch to return entire columns. Adds Data.TColumnData to
represent an entire column.
* Makes all fields in ExternalDataSource (except for status fields on
the result structures) optional in case fields become deprecated in
the future.
* Adds a limit parameter to the TOpenParams structure in case the
data source needs to apply the limit itself.

Adds the thrift structures for the public external data source API
and a new maven project containing the Java ExternalDataSource
interface and the generated Java thrift classes.
The ExternalDataSource.thrift structures can evolve in a backward
compatible way. The ExternalDataSource Java interface will always
contain a version number in the namespace (e.g.
com.cloudera.impala.extdatasource.v1 for V1) so we can potentially
make breaking changes to the interface in the future but still
support older versions.
A trivial implementation of the ExternalDataSource API is also
added for testing purposes.
TODO: Make the sample data source implementation realistic.
