• Prepared Titan->JanusGraph configuration

• 168 fixed some last minute issues in the CFN script and added a JanusGraph configuration for upgrading from Titan

• 169 made the build quicker and more verbose

• 170 to increase the cloud-init timeout

• 172 to speed up build

• 173 to fix service script

• 174 to add config to 1.0.0 branch

• 175 to add sdkman env to service script

• 176 export SDKMAN dir in service script

Test successful - was able to read and data in a Titan graph and Titan indexes using JanusGraph. Next, I was able to add data to the same graph using JanusGraph (graph of the gods) and read that data with Titan. Note that in the Graph of the Gods, the vertex ids and edge ids match exactly.
