* added config file implementation, refactoring * add gitignore * improved test * preperations for more metrics * added resource metrics * added first bgp metrics * added asn as label for bgp metrics * added prefix and message counts to bgp metrics * simplified * Update README.md * added yaml dependency * fixed go routine call * added timeout * clean up * added TLS support * set default api port for TLS * added routes metric * added missing log information * added type collectorContext to reduce the count of parameters for better readability * added DHCP and DHCPv6 metrics * filter for active dhcp leases only * added pool metrics * enable/disable feature in config file * refactoring * clean up * comment fix
