%% ejabberd_commands OAuth ReST ACL definition:
%% Two fields exist that are used to control access on a command from ReST API:
%% 1. Policy
%% If policy is:
%% - restricted: command is not exposed as OAuth Rest API.
%% - admin: Command is allowed for user that have Admin Rest command enabled by access rule: commands_admin_access
%% - user: Command might be called by any server user.
%% - open: Command can be called by anyone.
%%
%% Policy is just used to control who can call the command. A specific additional access rules can be performed, as
%% defined by access option.
%% Access option can be a list of:
%% - {Module, accessName, DefaultValue}: Reference and existing module access to limit who can use the command.
%% - AccessRule name: direct name of the access rule to check in config file.
%% TODO: Access option could be atom command (not a list). In the case, User performing the command, will be added as first parameter
%% to command, so that the command can perform additional check.
