Fix "Nagios ssh check is automatically added by the ssh module and cantains a wrong hostname on single node setup (Bug #5998)"

before, the ssh module added this check, resulting in a wrong
hostname and the port was always '22'.

manage_nagios parameter is boolean, so we use false instead of 'no'

manually add check_ssh to nagios (#5998)
Merge remote-tracking branch 'varac/5998_fix_nagios_nodename' into 0.5.3
Fix starting tapicero when it is not running (#6004)

Due to how tapicero's initscript is made, it is not possible to check
for a valid exit code for the status (it returns a zero when it is not
running). So we disable the puppet 'hasstatus' parameter and instead
puppet will look in the process table for 'tapicero'
