### Motivation C++ client Support KeyValue Schema. For key and value schema, just only support `AVRO` and `JSON` type(consistent with java client). This PR has been reviewed in pulsar repo: apache/pulsar#17125 ### Modifications - A new constructor is added in `SchemaInfo` to combine key and value schemas. - Add a new `KeyValue` class, to help users merge and parse key and value data.

…#121) ### Motivation When I ran the tests of Python wrapper in my local env, I observed a segmentation fault. See the key stacktrace: ``` #3 0x00007ffff6d742c5 in std::unique_lock<std::mutex>::lock() () from /usr/local/lib/python3.8/dist-packages/_pulsar.cpython-38-x86_64-linux-gnu.so #4 0x00007ffff6d72523 in std::unique_lock<std::mutex>::unique_lock(std::mutex&) () from /usr/local/lib/python3.8/dist-packages/_pulsar.cpython-38-x86_64-linux-gnu.so #5 0x00007ffff67de193 in pulsar::ClientImpl::newRequestId (this=0x0) at /home/xyz/github.com/apache/pulsar-client-cpp/lib/ClientImpl.cc:644 #6 0x00007ffff685d2c2 in pulsar::ConsumerImpl::~ConsumerImpl (this=0x7fff9800f9e0, __in_chrg=<optimized out>) at /home/xyz/github.com/apache/pulsar-client-cpp/lib/ConsumerImpl.cc:116 ``` In the destructor of `ConsumerImpl`, `client->newRequestId` might be called. However, `client` might be a null pointer because it's returned by `std::weak_ptr::lock()`. ### Modifications Add null check to avoid the segfault.

…#313) ### Motivation When libcurl is used in `AuthOauth2`, the `CURLOPT_NOSIGNAL` option is not set, i.e. it will be the default value so that the `Curl_resolv_timeout` function might crash in multi-threading environment. ``` #2 0xf630 in _L_unlock_13 from /lib64/libpthread.so.0 (0x34) #3 0x2e6c7f in Curl_failf from /usr/local/bin/***/libpulsar.so (0x6f) #4 0x30a285 in Curl_resolv_timeout from /usr/local/bin/***/libpulsar.so (0x95) ``` Since there are many duplicated code when calling curl C APIs, it's hard to notice that `CURLOPT_NOSIGNAL` is not configured in `AuthOauth2`. ### Modifications Introduce a `CurlWrapper` class that sets the same options to reduce the duplicated code and adapting consistent behaviors unless a few options.
