Description

ACCUMULO-3948 added a feature where you could define a context in the Accumulo configuration, not set it on a table, and use it in a Scanner. However, there is a runnable created n TabletServer.config() that runs every 60 seconds that closes context that are not defined on a table. Suggesting that we have the context cleaner not close any context defined in the configuration.
