----------------------------------------------------------------
WIP patch.
This allows the following usage pattern.
tez.am|task.log.level can now be specified as
{code}
DEBUG;org.apache.hadoop.ipc=INFO;org.apache.hadoop.security=INFO
{code}
General log level is DEBUG. hadoop.ipc, hadoop.security set to INFO level.
I'm planning to add a new parameter TEZ_TASK_SPECIFIC_LOG_LEVEL - which will
allow setting this up at a task level.
This could be done without affecting re-use - by completely re-initializing
runtime config, but that can be a follow up jira.
[~hitesh], [~rajesh.balamohan] - mind taking a look. Any thoughts on the
approach, or making this easier to use ?

> Currently, it's fairly difficult to configure logging beyond a generic log
> level. It'll be useful to have some control over which components need to be
> logged at a level / should be avoided. The IPC layer, for example, generates
> a lot of (multi-line) noise - which isn't useful when looking for Tez logs
> only.
