/**
* Checks are ember-data-model-fragments, so we can't just
* concat it, we have to loop through all the items in order to merge
* We also need to avoid repeating Node checks here as the service and the
* proxy is likely to be on the same node, without adding something extra here
* the node check will likely end up in the list twice.
*
* @param {Array} checks - Multiple lists of healthchecks to merge each one of the items in this array should be a further array of healthchecks
* @param {Boolean} exposed - Whether the checks should be marked as exposed via the proxy or not
* @param {Object} MMap - A MultiMap class. This is only exposed to allow for an easier interface but still allow an injectable MultiMap if we choose to do that during testing
* @returns {Array} - The final array of all of the healthchecks with any duplicate node checks removed, and also marked as exposed if required
