Description

When diagnosing memory-related issues, the first question we always ask is, "how much memory has Drill been given." This turns out to be rather tedious: we have to log onto the node running Drill, track down the config value, and check the configured amount. Since there are multiple possible config files, we have to figure out which was actually used.

An alternative is to do `ps aux | grep Drill` to look at the command line, but this also requires access to the node itself.

As an easier route, just as we display encryption information on the web UI main page, display the following:

Resources
Direct Memory: ## GB
Heap Memory: # GB
Cores: ##
