* Changed config and install options for Restconf
* clixon_restconf daemon is installed in /usr/local/sbin (as clixon_backend), instead of /www-data
* `configure --with-wwwdir=<dir>` remains but only applies to fcgi socket and log
* New option `CLICON_RESTCONF_INSTALL_DIR` is set to where clixon_restconf is installed, with default `/usr/local/sbin/`
* New option `CLICON_RESTCONF_INSTALLDIR` is set to where clixon_restconf is installed, with default `/usr/local/sbin/`
* Restconf drop privileges user is defined by `CLICON_RESTCONF_USER`
* `configure --with-wwwuser=<user>` is removed
* clixon_restconf drop of privileges is defined by `CLICON_RESTCONF_PRIVILEGES` option

### Minor features
* [Need an option to disable restconf mandatory action of overwriting startup_db #230](https://github.com/clicon/clixon/issues/230)
* Disable RFC 8040 mandatory copy of running to startup after commit
* Add default network namespace constant: `RESTCONF_NETNS_DEFAULT` with default value "default".
* CLI: Two new hide variables added (thanks: shmuelnatan)
* hide-database : specifies that a command is not visible in database. This can be useful for setting passwords and not exposing them to users.
