No longer ignore Linux virtual interfaces. Fixes redmine #1490, #3420
Update comment to reflect that all interfaces, not just virtual, listed in ignore_interfaces.rx may be skipped
This messge is a bit cryptic:
 * "Unacceptable model uncertainty examining processes"

This commit will show which process causes this issue:
 * "Unacceptable model uncertainty examining process(ganglia  20877     1 20877 17.3  3.2 2230968  0 1077096  3 01:17 01:48:23 /usr/sbin/gmond --pid-file /var/run/gmond.pid): `3 != 1077096  3`"
String change: Correct help text for cf-key.

License installation is only needed on the Enterprise hub, not on
managed hosts. The "without bootstrapping" comment makes no sense
anymore.
