* *: fix server grpc histograms (thanos-io#7493)

* Close endpoints after the gRPC server has terminated (thanos-io#7509)

Endpoints are currently closed as soon as we receive a SIGTERM or SIGINT.
This causes in-flight queries to get cancelled since outgoing connections
get closed instantly.

This commit moves the endpoints.Close call after the grpc server shutdown
to make sure connections are available as long as the server is running.

* Proxy: Query goroutine leak when `store.response-timeout` is set (thanos-io#7618)

time.AfterFunc() returns a time.Timer object whose C field is nil,
accroding to the documentation. A goroutine blocks forever on reading
from a `nil` channel, leading to a goroutine leak on random slow
queries.

* pkg/clientconfig: fix TLS configs with only CA (thanos-io#7634)

065e3dd introduced a regression: TLS configurations for Thanos Ruler
query and alerting with only a CA file failed to load.

For instance, the following snippet is a valid query configuration:

```
- static_configs:
  - prometheus.example.com:9090
  scheme: https
  http_config:
    tls_config:
      ca_file: /etc/ssl/cert.pem
```

The test fixtures (CA, certificate and key files) are copied from
prometheus/common and are valid until 2072.
