a86e40f320 scheduler: create public API and subsystem for scheduler/governor
This patch moves schedueler and governor related API from
the internal event.h to public scheduler.h.

With this it is possible to create subsystem responsible
for handling the schedulers.
Three schedulers and a governor were moved to scheduler modules
from event framework.

This will allow next patch to add JSON RPC configuration
to the whole subsystem.
Along with easier addition of other schedulers.

Removed debug logs from gscheduler, as they serve little purpose.

dde419084b event: Move json config loading to init
Loading subsystems and restoring state from a JSON config file is useful
outside of the SPDK application framework, so move it to lib/init.

9f62796127 event: Move RPC server initialization to init
I'm not sure whether this should go into lib/init or to lib/rpc
directly, but I've chosen lib/init for now.

This is to support applications that want to run the SPDK JSON
RPC server, but aren't using the SPDK application framework.

af935f768e event: Shift subsystem initialization code to a separate library
This is useful for applications even if they elect not to use the SPDK
event framework.

This doesn't shift everything in one go - just the subsystem
initialization logic. Configuration file loading also needs to move
in a separate patch later.

a20745541e reactor: add spdk_reactor_set_interrupt_mode func
spdk_reactor_set_interrupt_mode will send event to set
reactor into interrupt mode or poll mode, also set every
notify_cpuset on all reactors for consistency.
It can be used by RPC method or scheduler to set
reactor to interrupt mode while workload is lightweight.

Currently, this function is limited that the specific
reactor should have no attached spdk_thread.

344bb69312 event: remove printing legacy config for apps
Remove spdk_app_get_running_config() that allowed printing
legacy configuration by the apps.
Along with usr1_handler callback that was used to call that
function.

It was only used in iscsi_tgt so it is removed there.

The app_repeat test was using SIGUSR1 to trigger a
spdk_app_stop/spdk_app_start cycle.  But we can use
SIGTERM for that instead.  While here, do a bit of
cleanup in the app_repeat test app.
