CassExecProfile

[Lorak-mmk]

Useful feature of cppdriver that lets user create predefined set of options that can be then used with queries.

Rust driver doesn't support them - we need to decide if we want to implement it there, or fully in our wrapper. I'd be leaning towards implementation in the driver - the feature is useful in cppdriver, and could be useful in Rust driver, and could bring performance benefits.

This will be fixed when #107 is merged. Functions that will be left unimplemented should be added to the README under the limitations section.

First we need to add unsupported functions to README

[Gor027]

I have updated the list of the unimplemented functions. The Rust driver does not support blacklist/whitelist filtering, and as I understand shuffling replicas is always enabled. The cass_cluster_set_no_speculative_execution_policy function is implemented so I guess cass_execution_profile_set_no_speculative_execution_policy can be implemented similarly.

All the missing ones are part of the plan. We will have a new ticket per topic.
