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
