suggestion: display hobbit-client.cfg rules on the host info page

[John Glowacki]

Suggestion to add an option to see what hobbit-client.cfg rules that
apply for the host on the info page.

For example pyx01 might show something like this.

HOST=%pyx.*
    FILE    /var/adm/messages SIZE>1 MTIME<3600 yellow
    LOG     /var/adm/messages %(?-i)WARNING COLOR=yellow
"IGNORE=%WARNING: /var/adm/utmp exists"
    LOG     %.* %(?-i)NOTICE COLOR=yellow
    LOG     /var/adm/messages %NFS.*not.responding.still.trying COLOR=yellow
    LOG     /var/adm/messages %(?-i)REASON COLOR=red

HOST=pyx01
        DISK / 91 95

HOST=%.*
        DISK    /mnt 101 101
        DISK    %^/cdrom.* 101 101
        PROC    cron
        PROC    ntpd
        PROC    syslog

DEFAULT
        # These are the built-in defaults.
        UP      1h
        LOAD    5.0 10.0
        DISK    * 90 95
        MEMPHYS 100 101
        MEMSWAP 50 80
        MEMACT  90 97
