KUDU-1945 Auto-Incrementing Column, C++ client

This patch adds the first part of the cpp client side changes to the
auto incrementing column feature.

A new KuduColumnSpec called NonUniquePrimaryKey is added. Semantically
it behaves like PrimaryKey:
- only one column can have the NonUniquePrimaryKey ColumnSpec in a given
  KuduSchemaBuilder context,
- if it exists, it must be defined in the first place,
- compound keys are defined through a set function.
Functionally non-unique primary keys don't need to fulfill the
uniqueness constraint. An auto incrementing column is added in the
background automatically once a non-unique primary key is specified. The
non-unique keys and the auto incrementing columns together form the
effective primary key.
