Merge pull request #2067 from prometheus/superq/idle_jump
Handle small backwards jumps in CPU idle

Ben Kochie 73c9a10d37
Handle small backwards jumps in CPU idle
The Linux CPU idle stat can also jump backwards slightly in some cases.
Allow the jump back up to 3 seconds before we attempt to reset the CPU
counter cache.

Julien Pivotto 2e20d668f2 Only iniate collectors once
When /metrics is called for specific collectors, the collectors are
initialed every time. Which means that we spend a lot of time
re-initiating the same collectors again and again. Especially, some
collectors make the assumptions that that are initiated once - e.g.
systemd collector generates info message upon initiation.
