IMPALA-3819: Clarify stale block metadata warning message
We got user reports that the warning we display for stale block
metadata is confusing and gives an impression that it can cause
incorrect results. This commit clarifies the warning message.

> The Block locality stale warning message. ie.:
> WARNINGS: Read 348.13 MB of data across network that was expected to be local. Block locality metadata for table 'sometable' may be stale. Consider running "INVALIDATE METADATA `sometable`".
> Is misleading, it infers a data correctness issue where none exists. It should state that this issue carries only a performance impact and not a correctness one.
