MT#57531 support loading constants.yml

to prevent specifying db connections and (unencrypted)
credentials in the config.cfg file, we now support loading
it from constants.yml.

this can be enabled by specifying a path to constants.yml
in config.cfg, ie.

  constants_yml = /etc/ngcp-config/constants.yml

particular values can be overloaded, and the order of
precedence is as follows:

  1. values in config.cfg
  2. values in constants.yml
  3. values in provisioning.conf
  ...
