Improperly written pipes could be silently parsed as filter pipe.
For example, the following query:
* | by (x)
was silently parsed to:
* | filter "by" x
It is better to return error, so the user could identify and fix invalid pipe
instead of silently executing invalid query with `filter` pipe.

### Describe Your Changes
Currently, vmagent always uses a separate `http.Client` for every group
watcher in Kubernetes SD. With a high number of group watchers this
leads to large amount of opened connections.
This PR adds 2 changes to address this:
- re-use of existing `http.Client` - in case `http.Client` is connecting
to the same API server and uses the same parameters it will be re-used
between group watchers
- HTTP2 support - this allows to reuse connections more efficiently due
to ability of using streaming via existing connections.
See this issue for the details and test results -

### Describe Your Changes
evalInstantRollup could have overreport the number of fetched series if
`offset` checks will result into retry. This change updates fetched
series only if these checks were successful.
It also adds a comment to another potential place of over-reporting
series fetched. It doesn't fix it, because it would require spending
extra resources on such a check, while discrepancy in seriesFetched
doesn't affect calculations in any way.

This PR fixes#7062
For hijacked connections, one has to read from the connection buffer,
but still write directly to the connection. Otherwise, when reading
directly from such connections, the first byte may be lost. This, in
turn corrupts the ClientHello TLS handshake message and when the backend
server receives it, it closes the connection and reports the following
error in the log:
```
http: TLS handshake error from 127.0.0.1:33150: tls: first record does not look
like a TLS handshake
```
The first byte may be lost because underlying HTTP request handler may
read it from the connection and put it into the buffer. As the result,
subsequent connection reads won't see that byte.
- See: https://github.com/golang/go/issues/27408
