T5474: establish common file name pattern for XML conf mode commands
We will use _ as CLI level divider. The XML definition filename and also the Python helper should match the CLI node. Example: set interfaces ethernet -> interfaces_ethernet.xml.in set interfaces bond -> interfaces_bond.xml.in set service dhcp-server -> service_dhcp-server-xml.in (cherry picked from commit 4ef110fd2c501b718344c72d495ad7e16d2bd465)
