[1/9] accumulo git commit: ACCUMULO-3859 Ensure multiple
TableConfiguration instances are not created.
Repository: accumulo
Updated Branches:
refs/heads/1.6 6f7bf39b7 -> 55a9c8a99
refs/heads/1.7 44cd47035 -> bb73e90aa
refs/heads/master 633138205 -> 302617d04
ACCUMULO-3859 Ensure multiple TableConfiguration instances are not created.
If an instance of a TableConfiguration is cached which isn't the same
instance held by a Tablet, this will result in the Tablet never
receiving updates for constraints and more.
