Review request for atlas, Ashutosh Mestry, Bolke de Bruin, madhan, and Sarath Subramanian.


Changes
-------

modified installation instruction


Repository: atlas


Description
-------

Atlas does not support running Solr in standalone(http) mode.

It is especially useful for testing purposes to make setup as simple as possible without Zookeeper.
It also enables full integration with JanusGraph as it support both mode of running Solr `cloud`
and `http` https://docs.janusgraph.org/index-backend/solr/. Additional benefit is to decouple
hbase and solr while running embedded mode so that solr can be run in embbeded mode with external
hbase.

Proposed solution

call solr V1 API  while creating/updating request handlers in standalone solr
update atlas start script to enable standalone embedded solr

Reference to jira https://issues.apache.org/jira/browse/ATLAS-3654
Patch was applied against master branch
