Deprecate SecC modules from tsystemsmms

Hey guys,

we are no longer maintaining our SecC modules for Puppet and have moved to other solutions. These modules should be marked as deprecated.

For hardening purposes we now use dev-sec.io modules.

Alternatives are as follows:

• tsystemsmms-secc_os_linux -> hardening-os_hardening
• tsystemsmms-secc_sshd -> hardening-ssh_hardening
• tsystemsmms-secc_snmpd -> puppet-snmp (+ own hardening configuration)
• tsystemsmms-secc_nrpe -> pdxcat-nrpe (+ own hardening configuration)
• tsystemsmms-secc_nrpe_checks -> (none)
