Provide more information in the logs when distributed TLS requests fail

Bug report

What version of osquery are you using?

osquery 5.12.1

Currently, if distributed TLS requests to --distributed_tls_read_endpoint and --distributed_tls_write_endpoint fail on the TCP/IP or TLS layer, or if the JSON in the response could not be parsed, osquery shows nothing and retries (even when running with --verbose).

E.g. if osquery is configured with --distributed_tls_max_attempts=3 and the server is down or not returning a JSON response you just get:

265887 I0430 11:55:03.687932 29520 tls.cpp:263] TLS/HTTPS POST request to URI: https://example.com/api/v1/osquery/distributed/write
265891 I0430 11:55:05.651844 29520 tls.cpp:263] TLS/HTTPS POST request to URI: https://example.com/api/v1/osquery/distributed/write
265892 I0430 11:55:10.595957 29520 tls.cpp:263] TLS/HTTPS POST request to URI: https://example.com/api/v1/osquery/distributed/write

Which does not help for troubleshooting.

We should add some error logs when running with --verbose.
