CouchDB sdb Module

:maintainer:    SaltStack
:maturity:      New
:depends:       python2-couchdb
:platform:      all

This allow interaction between Salt and a CouchDB [couchdb.apache.org]
database. It uses salt's `sdb` system to allow for inserts and retrevals
using the `sdb://` prefix in salt configuration files.

To use the couchbase sdb module, it must first be configured in the salt
master or minion config. The following arguments are required:

.. code-block:: yaml

couchdb_sdb:
      driver: couchdb
      host: localhost
      port: 5984
      database: salt_sdb

One could then query the CouchDB instance via an `sdb://` URI such as the
following:

.. code-block:: yaml

password: sdb://couchdb_sdb/mykey

To use this interface, you must track IDs on your own or have another source
to do the map-reduce logic necessary to calculate the ID you wish to fetch.

Additional contributions to build true map-reduce functionality into this module
would be welcome.
