Create/Add Campaigns Key

[deezone]

When campaign data is cached create/add an index key with a list of all campaigns cached.

• When campaign is added through POST /campaign create / add to the index key of all the campaign cached values: [nid]-[language]-[expiry timestamp].

  Storing Sets: Sets are similar to lists, but the difference is that they don’t allow duplicates.

  The first item of the array represents the name of the key while the rest represent the
  elements of the list.

client.sadd(['tags', 'angularjs', 'backbonejs', 'emberjs'], function(err, reply) {
    console.log(reply); // 3
});

Not needed as the /api/v1/campaign GET will return a 404 response if a key is not found. Use response to indicate that the entry needs to be built and stored.
