0.17.2 - Fix critical index inefficiency in Janusgraph Setup

Docker image/tag: semitechnologies/weaviate:0.17.2

Fixes

• Critical Indexing inefficiency in Janusgraph Setup (#939)
  This releases fixes a critical issue where Janusgraph would do a (very inefficient) whole graph traversal, rather than efficiently use the attached index - often leading to request timeouts.

Notes

• Because of the criticality of this fix, it is fixed in releases 0.16.x, 0.17.x, 0.18.x and 0.19.x while usually only the latest release is supported.
