Allow to configure snmpd_config

Expose a new Puppet parameter to snmp profile, ``snmpd_config`` which
is an array definded to undef by default.
It can be used to override all snmpd configuration for advanced
deployments.
If used, all parameters have to be configured included users and
passwords, which should be the same as given to snmpd_password
and snmpd_user. There is no logic that will verify the content
of ``snmpd_config``.

Example of hieradata which configures snmpd_config:
  snmpd_config:
    - 'createUser ro_snmp_user MD5 "secrete"',
    - 'rouser ro_snmp_user'
    - 'proc neutron-server'
    - 'proc nova-api'
