IMPALA-8401: SIGRTMIN initiates the graceful shutdown process
This patch enables a user that has access to the impalad process,
to initiate the graceful shutdown process with a deadline of one year
by sending SIGRTMIN signal to it.
Sample usage: "kill -SIGRTMIN <IMPALAD_PID>"
Testing:
Added relevant e2e tests.
Tested on CentOS 6, CentOS 7, Ubuntu 16.04, Ubuntu 18.04 and SLES 12

> Project: IMPALA
> Issue Type: Bug
> Reporter: Bikramjeet Vig
> Assignee: Bikramjeet Vig
> Priority: Major
>
> Once the shut down process is initiated, impalad would stop accepting any new
> connections or queries. This makes it difficult if a user wants to shut down
> impalad across a cluster via the shutdown command. For eg. the user would
> need to make sure to send the command to all executors before sending them to
> the coordinators. Adding a mechanism to initiate the graceful shutdown
> process with a large deadline by sending a SIGQUIT to the impalad process
> would make cluster management simpler.
