    METRON-739 Create Local Profile Runner

    Troubleshooting issues when programming against a live stream of data can be difficult.
 This is the primary reason that drove the creation of the REPL.  Similarly it would be useful
to have a means to run a profile locally to troubleshoot, validate, or debug a profile.  Now
you can, right in the REPL!
    Take it for a test spin.  
    1.  Create your profiles.  For this example, In the editor copy/paste in the basic "Hello,
World" profile.
        [Stellar]>>> conf := SHELL_EDIT()
          "profiles": [
              "profile": "hello-world",
              "onlyif":  "exists(ip_src_addr)",
              "foreach": "ip_src_addr",
              "init":    { "count": "0" },
              "update":  { "count": "count + 1" },
              "result":  "count"
    1.  Initialize the Profiler.
        [Stellar]>>> profiler := PROFILER_INIT(conf)
        [Stellar]>>> profiler
    1. Create some telemetry.   In the editor, copy/paste in the message JSON.
        [Stellar]>>> message := SHELL_EDIT()
        [Stellar]>>> message
          "ip_src_addr": "",
          "protocol": "HTTPS",
          "length": "10",
          "bytes_in": "234"
    1. Apply some telemetry messages to your profiles.
        [Stellar]>>> PROFILER_APPLY(message, profiler)
        [Stellar]>>> PROFILER_APPLY(message, profiler)
        [Stellar]>>> PROFILER_APPLY(message, profiler)
    1. Flush the profiles, to see what it has calculated.  The result is a list of profile
measurements.  Each value is a map containing detailed information about the profile measurements
that were taken.
        [Stellar]>>> values := PROFILER_FLUSH(profiler)
        [Stellar]>>> values := PROFILER_FLUSH(profiler)
        [Stellar]>>> values
        [{period={duration=900000, period=1669628, start=1502665200000, end=1502666100000},

           profile=hello-world, groups=[], value=3, entity=}]
    I have added unit tests to cover all of the functionality, have tested the new Stellar
functions in the REPL and have also completed a basic regression test for the Profiler itself.
