Implement second part of dynamic DMaaP config
VESCollector app can now fetch CBS configuration and rebuilt the part regarding sending events dynamically, without restarting application. Application will still be restarted by a .sh script, if there were changes regarding collector.properties file. The decision of whether dynamic configuration should be triggered is now based on existence of env vars CONSUL_HOST, CONFIG_BINDING_SERVICE, HOSTNAME, not as previously on CBSPOLLTIME. Frequency at which the config check should happen is now exposed via property from collector.properties Change-Id: I98ff160fa51d08d84a23c716d90ceaacbe17ada6 Signed-off-by: PawelSzalapski <pawel.szalapski@nokia.com> Issue-ID: DCAEGEN2-519
