Odyssey 1.3 released

Odyssey team is pleased to announce the release of Odyssey 1.3, a scalable multi-threaded connection pooler for PostgreSQL\GreenplumDB designed for the cloud.

In this release:

* Support for protocol-level prepared statements in transaction pooling mode. You can enable [pool_reserve_prepared_statement](https://github.com/yandex/odyssey/blob/136dcca1a4fa8f92094b86132133272bbc444b2d/config-examples/odyssey-dev.conf#L87) for a database. For client sessions issuing prepared statements Odyssey will automatically prepare those statements in database processes when necessary.
* Standby lag polling. You can configure [watchdog query](https://github.com/yandex/odyssey/blob/136dcca1a4fa8f92094b86132133272bbc444b2d/config-examples/odyssey-dev-with-watchdog.conf#L54) for a database, and Odyssey will automatically prevent reading stale data.
* A number of small bug fixes and improvements.
