Clicktail installed from provided .deb package (version 1.0.20180402) generates HTTP requests like:

`POST /?query=INSERT+INTO+clicktail.apache_log+FORMAT+JSONEachRow HTTP/1.1`
`Host: XXX:8123`
`User-Agent: libclick-go/1.4.0 clicktail/dev (regex)`
`Content-Length: 2425`
`Authorization: Basic XXX`
`Content-Encoding: gzip`
`Content-Type: application/json`
`X-Honeycomb-Team: `
`Accept-Encoding: gzip`

Header X-Honeycomb-Team contains only space before terminal characters:
`58 2d 48 6f 6e 65 79 63 6f 6d 62 2d 54 65 61 6d 3a 20 0d 0a`

Clickhouse server 21.4.5.46 doesn't accept those requests and returns: 
`HTTP/1.1 400 Bad Request`

There is no requirement in RFC 7230 https://tools.ietf.org/html/rfc7230#section-3.2 for field-value to contains any data. Shouldn't be those requests accepted?
