Support TableView

[BewareMyPower]

Fixes #217

Upgrade the C++ client to 3.7.1 to include this fix: apache/pulsar-client-cpp#487

Compared to the Java TableView API, only a few methods are added.

keySet(), values() and entrySet() can be implemented by for_each. Take entrySet() for example:

        entries = dict()
        table_view.for_each(lambda key, value: entries.__setitem__(key, value))

isEmpty() can be implemented by __len__() and containsKey() can be implemented by get().

listen() and refresh() are not added because it's also missed in the C++ client.

We need to wait https://dist.apache.org/repos/dist/release/pulsar/pulsar-client-cpp-3.7.1/ to be synchronized to https://archive.apache.org/dist/pulsar/. For now, I used the previous URL. I will revert ba3684b after it's synchronized.
