Bitwise operator in InfluxQL don't work in QueryNode

The bitwise operators (&, |, ^) are not accepted when you write a InfluxQL query in a Kapacitor script.

**Kapacitor version used:** 1.5.0
**Influx version:** 1.6.0

Example script:
```
var my_var = batch
|query('''
SELECT "boolean_value" | TRUE as my_value
FROM "my_db"."autogen".my_measurement
''')
.period(1h)
.every(1m)
.align()
.groupBy('my_tag')
```

Error:
```
failed to parse InfluxQL query: found |, expected FROM at line 2, char 41
```
The same query works perfectly on the influx CLI.

Start at the QueryNode InfluxQL parsing path and compare how the example query is handled there with the working Influx CLI behavior. Reproduce the reported bitwise-operator error using the supplied script; done means &, |, and ^ queries are accepted by QueryNode without the shown parse failure.
