ACLS
~~~~
For more information about acls, please checkout the kazoo documentation.
http://kazoo.readthedocs.io/en/latest/api/security.html#kazoo.security.make_digest_acl
The following options can be included in the acl dictionary:
:param username: Username to use for the ACL.
:param password: A plain-text password to hash.
:param write: Write permission.
:type write: bool
:param create: Create permission.
:type create: bool
:param delete: Delete permission.
:type delete: bool
:param admin: Admin permission.
:type admin: bool
:param all: All permissions.
