Add NACM rules
NACM completely bypasses sysrepo permissions, so some rules need to be
set up. Now that the default shell for non-root users is netconf-cli, we
can completely forget about the sysrepo permissions, and only focus on
NACM. The default configuration for everyone is to allow reading and
disallow writing of everything. This patch changes this to allow root to
do anything and also allow the dwdm user to manipulate a subset of
installed modules.
