Refactor exection of runs

[vpetersson]

tl;dr: We need more granular control over what's run and when. Some checks need to run often, others not very frequently.

I want to have three different intervals for various checks:

• Every five minutes
• Every hour
• Every day

Here's a draft for the frequency of the runs:

Function	Frequency	Trigger
device_operating_system_version: platform.release()	Daily
fqdn: socket.getfqdn()	Daily
ipv4_address: get_primary_ip()	Hourly
uptime: get_uptime()	Hourly
agent_version: str(version)	Hourly
installation: detect_installation().name	Daily
os_release: rpi_helper.get_os_release()	Daily
packages: get_deb_packages()	Hourly
connections ports: security_helper.netstat_scan()	Hourly
blocklist: ping	Daily
iptables_helper.block(blocklist)	Daily	Boot
processes: security_helper.process_scan()	Hourly
logins: journal_helper.logins_last_hour()	Hourly
firewall_rules: iptables_helper.dump()	Hourly	Change in Dash
scan_info: ports	Hourly
netstat: connections	Hourly
selinux_status: security_helper.selinux_status()	Daily
app_armor_enabled: security_helper.is_app_armor_enabled()	Daily
default_password: security_helper.check_for_default_passwords(CONFIG_PATH)	Daily
audit_files: security_helper.audit_config_files()	Hourly
auto_upgrades: rpi_helper.auto_upgrades_enabled()	Hourly
mysql_root_access: security_helper.mysql_root_access()	Hourly
kernel_package: rpi_helper.kernel_deb_package()	Hourly
cpu: security_helper.cpu_vulnerabilities()	Hourly
device_manufacturer: Raspberry Pi	Daily
device_model: rpi_metadata[hardware_model]	Daily

In the future, we will also need support for events/functions triggered from the server.
