[portmgrd]: Fix setting default port admin status and MTU (#691)

This commit moves setting of default admin status and mtu to portmgrd to be aligned with other managers (e.g. teammgrd). It also fixes "N/A" admin status in "show interface status" output for ports which have no 'admin_status' field in config DB. Signed-off-by: Stepan Blyschak <[email protected]>
