2.1 still catching Error's

`grep -R Error * | grep java | grep -i catch | grep -v AssertionError` on the source yields:

```
core/src/main/java/org/apache/accumulo/core/client/admin/NewTableConfiguration.java: } catch (LocalityGroupConfigurationError e) {
core/src/main/java/org/apache/accumulo/core/util/LocalityGroupUtil.java: } catch (LocalityGroupConfigurationError | RuntimeException e) {

```

Need to evaluate these to see if we should fix these.

Start with the grep results and inspect each listed catch in NewTableConfiguration.java, LocalityGroupUtil.java, the operations implementations, TServerUtils.java, FileCompactor.java, NativeMapLoader.java, Tablet.java, MinorCompactor.java, and TabletClientHandler.java. Determine which broad Error or related catches should change and document or implement the decisions consistently. Done means every reported catch has been evaluated and the necessary fixes are covered by the relevant tests.
