    DRILL-4455: Depend on Apache Arrow

    Remove the vector and memory modules
    Replace most instances of TypeProtos.MajorType, TypeProtos.MinorType etc
      with corresponding org.apache.arrow.types.Types class.
    The code for serializing and deserializing vectors is still in the Drill code-base
      and still uses the old TypeProtos classes. The class MajorTypeHelper is used
      to convert between the two sets of classes.
    The old load and getMetadata classes in ValueVector are now found in a corresponding
      ValueVectorHelper class

>             Fix For: 1.7.0
>
>
> The code for value vectors and memory has been split and contributed to the apache arrow
repository. In order to help this project advance, Drill should depend on the arrow project
instead of internal value vector code.
> This change will require recompiling any external code, such as UDFs and StoragePlugins.
The changes will mainly just involve renaming the classes to the org.apache.arrow namespace.
