  - Merge "VES: add new tag to strip extra dashes"
  - VES: add new tag to strip extra dashes

    The `!StripExtraDash` tag can be used in YAML configuration
    file to strip extra dashes in the YAML filed value. This may
    happen if some of the collectd plugin field (plugin_instance,
    type_instace etc.) is set to empty value but the field is
    specified in the YAML configuration file. For instance:

    "{vl.plugin_instance}-{vl.type_instance}"

    The result fo the example above can be string consisting
    extra dashes if `type_instace` field is not set by a collectd
    plugin:

    "load-"
