  [conf completion]: T1779: Add tunnels to completion
  [XML templates] T1772: Changed old hacks to proper regex, according to the fix
  Add a function for retrieving config dicts.
  snmp: make script extension code more readable
  snmp: use proper stat literals on chmod()
  snmp: fix verify() indent on script extensions
  snmp: fix verify() bail out early order
  snmp: T1738: cleanup import statements
  T1759: Fixing dependency bug from previous commit
  T1773, T1774: add a show config operation with JSON and raw options.
  T1759: Merging interface.py into ifconfig.py
  Allow list arguments in the vyos.config show_config() function.
  Replace the try and wait for segfault approach with explicit inSession check.
  T1773: add a script for converting the config to JSON. It also exposes those functions in vyos.configtree
  [XML templates] T1772: Add escaping of `\` symbol in `<regex>`
