Release 2.5.0

This release adds major new features since the 2.4.2 release.
We deem it moderate priority for upgrading

This release adds several and long-awaited/wanted features:

* Continuous Aggregates for Distributed Hypertables
* Support for PostgreSQL 14
* Experimental: Support for timezones in `time_bucket_ng()`, including
the `origin` argument

This release also includes several bug fixes.

**Major Features**
* timescale#3435 Add continuous aggregates for distributed hypertables
* timescale#3034 Add support for PostgreSQL 14
* timescale#3505 Add support for timezones in `time_bucket_ng()`

**Minor Features**
* timescale#3598 Improve evaluation of stable functions such as now() on access
node

**Bugfixes**
* timescale#3580 Fix memory context bug executing TRUNCATE
* timescale#3654 Fix index attnum mapping in reorder_chunk
* timescale#3661 Fix SkipScan path generation with constant DISTINCT column
* timescale#3708 Fix crash in get_aggsplit
* timescale#3709 Fix ordered append pathkey check
* timescale#3728 Fix SkipScan with varchar column

**Thanks**
* @binakot and @sebvett for reporting an issue with DISTINCT queries
* @hardikm10, @DavidPavlicek and @pafiti for reporting bugs on TRUNCATE
* @mjf for reporting an issue with ordered append and JOINs
* @phemmer for reporting the issues on multinode with aggregate queries
and evaluation of now()
