    Options:
      --filter filterExpr    Restricts the list to the NS instances matching the filter

    \b
    filterExpr consists of one or more strings formatted according to "simpleFilterExpr",
    concatenated using the "&" character:

      \b
      filterExpr := <simpleFilterExpr>["&"<simpleFilterExpr>]*
      simpleFilterExpr := <attrName>["."<attrName>]*["."<op>]"="<value>[","<value>]*
      op := "eq" | "neq" | "gt" | "lt" | "gte" | "lte" | "cont" | "ncont"
      attrName := string
      value := scalar value

    \b
    where:
      * zero or more occurrences
      ? zero or one occurrence
      [] grouping of expressions to be used with ? and *
      "" quotation marks for marking string constants
      <> name separator

    \b
    "AttrName" is the name of one attribute in the data type that defines the representation
    of the resource. The dot (".") character in "simpleFilterExpr" allows concatenation of
    <attrName> entries to filter by attributes deeper in the hierarchy of a structured document.
    "Op" stands for the comparison operator. If the expression has concatenated <attrName>
    entries, it means that the operator "op" is applied to the attribute addressed by the last
    <attrName> entry included in the concatenation. All simple filter expressions are combined
    by the "AND" logical operator. In a concatenation of <attrName> entries in a <simpleFilterExpr>,
    the rightmost "attrName" entry in a "simpleFilterExpr" is called "leaf attribute". The
    concatenation of all "attrName" entries except the leaf attribute is called the "attribute
    prefix". If an attribute referenced in an expression is an array, an object that contains a
    corresponding array shall be considered to match the expression if any of the elements in the
    array matches all expressions that have the same attribute prefix.

    \b
    Filter examples:
       --filter  admin-status=ENABLED
       --filter  nsd-ref=<NSD_NAME>
       --filter  nsd.vendor=<VENDOR>
       --filter  nsd.vendor=<VENDOR>&nsd-ref=<NSD_NAME>

      --ns     TEXT           NS instance id or name to restrict the VNF list

    \b
    filterExpr consists of one or more strings formatted according to "simpleFilterExpr",
    concatenated using the "&" character:

      \b
      filterExpr := <simpleFilterExpr>["&"<simpleFilterExpr>]*
      simpleFilterExpr := <attrName>["."<attrName>]*["."<op>]"="<value>[","<value>]*
      op := "eq" | "neq" | "gt" | "lt" | "gte" | "lte" | "cont" | "ncont"
      attrName := string
      value := scalar value

    \b
    where:
      * zero or more occurrences
      ? zero or one occurrence
      [] grouping of expressions to be used with ? and *
      "" quotation marks for marking string constants
      <> name separator

    \b
    "AttrName" is the name of one attribute in the data type that defines the representation
    of the resource. The dot (".") character in "simpleFilterExpr" allows concatenation of
    <attrName> entries to filter by attributes deeper in the hierarchy of a structured document.
    "Op" stands for the comparison operator. If the expression has concatenated <attrName>
    entries, it means that the operator "op" is applied to the attribute addressed by the last
    <attrName> entry included in the concatenation. All simple filter expressions are combined
    by the "AND" logical operator. In a concatenation of <attrName> entries in a <simpleFilterExpr>,
    the rightmost "attrName" entry in a "simpleFilterExpr" is called "leaf attribute". The
    concatenation of all "attrName" entries except the leaf attribute is called the "attribute
    prefix". If an attribute referenced in an expression is an array, an object that contains a
    corresponding array shall be considered to match the expression if any of the elements in the
    array matches all expressions that have the same attribute prefix.

    \b
    Filter examples:
       --filter  vim-account-id=<VIM_ACCOUNT_ID>
       --filter  vnfd-ref=<VNFD_NAME>
       --filter  vdur.ip-address=<IP_ADDRESS>
