Description

Community agrees we should change Elasticsearch default binding to "all interfaces" (0.0.0.0).

In addition, taking opportunity to fix the problem with square brackets on these parameters:

• zen_discovery_ping_unicast_hosts
• network_host

For all other parameters in ES and other Metron sub-components, the square brackets around lists are not needed in the parameter value, but are instead provided in the template text. Making it so here, with the additional step that if the user provides them (due to old habit) the extra square brackets will be stripped before they cause a problem. This should make the change less backward-incompatible.
