Get a value from a db, using a uri in the form of sdb://<profile>/<key>. If
the uri provided does not start with sdb://, then it will be returned as-is.
CLI Example:
.. code-block:: bash
salt '*' sdb.get sdb://mymemcached/foo

def set_(uri, value):
'''
Set a value in a db, using a uri in the form of ``sdb://<profile>/<key>``.
If the uri provided does not start with ``sdb://`` or the value is not
successfully set, return ``False``.
CLI Example:
.. code-block:: bash
salt '*' sdb.set sdb://mymemcached/foo bar

Delete a value from a db, using a uri in the form of ``sdb://<profile>/<key>``.
If the uri provided does not start with ``sdb://`` or the value is not
successfully deleted, return ``False``.

'''
Perform a one-time generation of a hash and write it to sdb.
If that value has already been set return the value instead.
This is useful for generating passwords or keys that are specific to
multiple minions that need to be stored somewhere centrally.
State Example:
.. code-block:: yaml
some_mysql_user:
mysql_user:
- present
- host: localhost
- password: '{{ salt['sdb.get_or_set_hash']('some_mysql_user_pass') }}'
CLI Example:
.. code-block:: bash
salt '*' sdb.get_or_set_hash 'SECRET_KEY' 50
.. warning::
This function could return strings which may contain characters which are reserved
as directives by the YAML parser, such as strings beginning with ``%``. To avoid
issues when using the output of this function in an SLS file containing YAML+Jinja,
surround the call with single quotes.
