Alexander Tkachev 8484273f36 CLOUD: Fix "-Wcast-qual"
The passed buffer is not changed, so could be `const`.

You might see that `postFields.c_str()` is `buffer`. Yet, as it's
`postFields`, it's used for POST in curl_easy_setopt(), which copies the
passed buffer. When `buffer` is used for upload, it's an actual bytes
buffer, kept in CurlRequest.
