METRON-420 Add Expiration to Profile Definition

[nickwallen]

The user can specify an expiration for each profile definition. This field is optional. All documentation and tests have been updated.

Added the expires field to README example 1.

{
  "inputTopic": "indexing",
  "profiles": [
    {
      "profile": "example1",
      "foreach": "ip_src_addr",
      "onlyif": "protocol == 'HTTP'",
      "init": {
        "total_bytes": 0.0
      },
      "update": {
        "total_bytes": "total_bytes + bytes_in"
      },
      "result": "total_bytes",
      "expires": 30
    }
  ]
}

The expires field is currently defined as the number of days. It would be nice to specify '30 days', '6 months', or '2 years', but I will leave that work for another day.

Depends on the following PRs.

• METRON-418 Set TTL on HBase Puts #251
• METRON-419 Update Tuple to HBase Mapper/Bolt to Set TTL #252
