primary key set to allow null

[Mark McClain]

The IPAvailabilityRange model declared allocation_pool_id as nullable and as a component of the primary_key. Under the hood, the primary_key declaration conflicts with the nullable attribute and causes the nullable attribute to be set to False within the database. The model should be updated to be consistent with proper SQL.

    set allocation_pool_id nullable=False

    fixes bug 1103216

    SQL Primary Keys cannot be null, so this patch fixes an
    inconsistency between the models and SQL. The databases were
    correcting this automatically, so a migration is not required.
