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.
