Revert "Merge branch 'cprice-puppet-bug/3.0rc/15187-log-fatal-errors-to-console'"

This reverts commit 8d99bcbe6ebe6ca15868334bb52349911b58598c, reversing
changes made to 7d6515f076715c1feab0addc99312c42fb8b578c.

This change had two unintended side effects:

1) 20900 tagmail from 'puppet agent --onetime' run as a cron job begins
sending additional emails of verbose logs.

2) 20919 cron job of 'puppet agent --onetime --no-daemonize' produces
additional verbose logs to both console and syslog.

Issue #1 occured because the 15187 patch caused agent log level to
switch to info by default.

Issue #2 was due to the above log level issue, and the fact that by
default a console logger was also opened for all agents, which does not
get closed if --no-daemonize is specified.

Reverting fixes both of these unintended logging issues by returning to
the logging behavior seen in 3.1.1.
