Closing temporarily to avoid unnecessary load on the CI. Will reopen when I'm actively working on the PR again.

This requires openssl.

/home/conan/w/prod-v1/bsr/48/+6d3bb/.conan/data/azure-storage-cpp/7.5.0/_/_/source/src/Microsoft.WindowsAzure.Storage/src/hashing.cpp:268:51: warning: ‘int SHA256_Final(unsigned char*, SHA256_CTX*)’ is deprecated: Since OpenSSL 3.0 [-Wdeprecated-declarations]
         SHA256_Final(m_hash.data(), m_hash_context);

I believe it was automagically grabbing the openssl which was required by cpprestsdk in the past, but now that's not being passed in. We could either add the "transitive_header=True" argument to cpprestsdk's openssl, or require openssl for this package as well.

Given that the azure-storage-cpp code directly includes openssl on non-windows platforms, I think we should add a requires to this recipe.

if self.settings.os != "Windows":
    self.requires("openssl/[>=1.1 <4]")

This is the usage.

// Microsoft.WindowsAzure.Storage/includes/wascore/hashing.h
#ifdef _WIN32
#include <BCrypt.h>
#else
#include <openssl/sha.h>
#include <openssl/md5.h>
#include <openssl/hmac.h>
#endif

One of the remaining green migration PRs. Another review would be welcome.
