Missing support on some label filter functionality.

[gwdawson]

Three points where missed when implementing the logql formatter, these are:

• LabelFilter !and And LabelFilter
• LabelFilter !or Or LabelFilter
• LabelFilter !and "," LabelFilter

---

Example for LabelFilter !and And LabelFilter:

QUERY:
{source="data"} | logfmt | labelA="" and labelB=""


EXPECTED:
{source="data"}
  | logfmt
  | labelA="" and labelB=""


ACTUAL:
{source="data"}
  | logfmt
   | labelA="" | labelB=""

---

Example for LabelFilter !or Or LabelFilter:

QUERY:
{source="data"} | logfmt | labelA="" or labelB=""


EXPECTED:
{source="data"}
  | logfmt
  | labelA="" or labelB=""


ACTUAL:
{source="data"}
  | logfmt
   | labelA="" | labelB=""

---

Example for LabelFilter !and "," LabelFilter:

QUERY:
{source="data"} | logfmt | labelA="", labelB=""


EXPECTED:
{source="data"}
  | logfmt
  | labelA="", labelB=""


ACTUAL:
{source="data"}
  | logfmt
   | labelA="" | labelB=""
