event consumption needs to be disabled on gnocchi dispatcher

[gordon chung]

we constantly throw event errors on gnocchi backend because default collector pulls from both sample and event queue.

we should ideal not pull from event queue with gnocchi collector. ie. have an event collector and a sample collector. or we need to document that events and samples need to be published to specific topics and collectors pull from said topics.

    Configure collector to only record meter or event

    Added the configuration options to allow the administrator to configure
    the collector to only record meter or event by setting the
    meter_dispatchers and event_dispatchers configuration.

    Separated dispatcher managers load the dispatchers from different
    namespaces for meter/event respectively.

    Doc-Impact: separated meter/event dispatchers

    Docs: Configure meters/events dispatch separately

    This is a docs change in support of Change-Id:
    I161318f4503ce79205b54a93f2ae9b4e052f7971

    Dispatchers now only record meter or event data and are configured
    independently. The install guide is updated to reflect this
    distinction. Because the referenced Change-Id used Doc-Impact
    as a flag instead of the non-hyphenated variant there is no
    independant bug in the OpenStack Manuals project for this change.

    Additionally, existing content for configuring Gnocchi is broken out
    into more detail.
