IMPALA-8245: Add hostname to the error message in HdfsMonitoredOps
When a task submitted via HdfsMonitoredOps fails, it raises
TErrorCode::THREAD_POOL_TASK_TIMED_OUT or
TErrorCode::THREAD_POOL_SUBMIT_FAILED errors. The error generated
calls GetDescription() to provide information about the failed
hdfs operation. This change appends the hostname to the description
to enable the user to easily identify the host which has reached a
bad connection state with the NameNode.
Testing:
Modified the test_hdfs_timeout.py to ensure that the hostname is
logged in the error message.

> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.2.0
> Reporter: Joe McDonnell
> Assignee: Pooja Nilangekar
> Priority: Major
>
> If a DiskIo operation times out, it generates a
> TErrorCode::THREAD_POOL_TASK_TIMED_OUT or
> TErrorCode::THREAD_POOL_SUBMIT_FAILED error codes. These call
> GetDescription() to get DiskIo related context. That information should
> include the hostname where the error occurred to allow tracking down a
> problematic host that is seeing DiskIo timeouts.
