ASM-1161: deploy nagios check scripts and cron job

Rather than hacky fixes in the applicationConfigureVM part of
asm-automation which would most likely break during upgrades this
changes the asm-deployer rpm to depend on nagios (now in the base vm)
and to put the nagios plugins, cron job and enables the service when
asm-deployer gets installed
ASM-1161: permission fixes

Fix some permissions to make cron happy
Merge pull request #3 from ripienaar/nagios_integration
