[tuned] #49: Provide a way to disable dynamic updates per plugin

#49: Provide a way to disable dynamic updates per plugin

I use synergy to share a mouse & keyboard between my desktop and laptop.
Whenever I start to download something (for example a Fedora ISO), I lose
my connection for about 30 sec due to the ethernet interface speed change.
Even worse the download fails because the connection is lost for this
brief period of time. I'd suggest that at least this change doesn't occur
when on AC as a default policy, but for me personally a way to disable
dynamic updates per plugin without having to hack the python code would be
nice. I couldn't seem to find anywhere in the documentation that mentions
how to do this.

NO_HZ FULL will not work in realtime-virtual-guest
by Yang, Tao Y
Hi ALL,
I am running the RHEL 7.1 in both host and guest for a low latency network performance test.
I use the realtime-virtual-host for the host and realtime-virtual-guest for guest.
These optimize really improve my network performance in the RFC 2544 throughput test.
But I fund there are error in the guest OS, when I enable the nohz_full.
Looks like the nohz_full can't be enable in the guest OS.
Do we need remove the nohz_full in the realtime-virtual-guest for guest?
Here is information from the Guest OS.
