Subject: [PATCH] httpc: use http 1.1 by default
Commit 0ea1ba877b8e ("third_party: update libcurl from 8.3.0 to 8.4.0")
bumps libcurl version and bringed a regression: http client returns
nothing using connection with HTTP/2 protocol. The problem could be
reproduced by etcd-client, see description in issue [1]. The problem in
http client is due to commit "h2: testcase and fix for pausing h2
streams" [2] in libcurl. With reverted commit in libcurl the problem is
gone.
To work around the issue, commit sets HTTP 1.1 as default protocol in
http client.
Needed for #9547
