v0.69.0

This release contains a mix of features, bugfixes and necessary tooling and test changes required to support the upcoming OPA 1.0 release.

Inter-Query Value Cache (#6908)

OPA now has a new inter-query value cache added to the SDK. It is intended to be used for values that are expensive to compute and can be reused across multiple queries. The cache can be leveraged by built-in functions to store values that otherwise aren't appropriate for the existing inter-query cache; for instance when the entry size isn't an appropriate or primary limiting factor for cache eviction.

The default size of the inter-query value cache is unbounded, but can be configured via the caching.inter_query_builtin_value_cache.max_num_entries configuration field. OPA will drop random items from the cache if this limit is exceeded.

The cache is used by the regex and glob built-in functions, which previously had individual, non-configurable caches with a max entry size of 100 each.

Currently, the cache is only exercised when running OPA in server mode (ie. opa run -s). Also this feature is unsupported for WASM.
