(PDB-247) Fixes the namespace override warnings from schema

Schema 0.2.0 has not yet been released, but has the fix for PDB-247. I
made a pre-release (0.2.0-pre-1) of the current state of the branch and
updated PuppetDB to use it.  Some PuppetDB code also needed to change as
one of the protocols is changing in 0.2.0.

(PDB-247) Fixes the namespace override warnings from schema
PDB-279 Sanitize report imports

Previously we had a bug PDB-85 that caused our exports on 1.5.x to fail. This
has been fixed, but alas people are trying to import those broken dumps into
1.6.x and finding it doesn't work.

This patch sanitizes our imports by only using select keys from the reports
model and dropping everything else.

PDB-303 Utilise final version of prismatic/schema 0.2.0

Previously we were using our own published version of a pre 0.2.0 release, this
patch remedies that to now point at the upstream finalized version.
