v.7.10.0

Improvements:

1. [LUNA-8219] Added support for advanced filtering with new operators and JSON data type for meta field in events and event field in general events.

   New operators:

   • contains - checks if all elements of the provided value are contained in the event field

   • ncontains - negation of contains operator

   • overlaps - checks if at least one element from the array overlaps with the event field

   • noverlaps - negation of overlaps operator

   New data type (in the query params to filter events):

   • json - allows filtering by JSON objects and arrays (values must be URL-encoded JSON strings)

   Extended operators:

   Existing operators eq, neq, in, nin now support :json type - enabling exact match for JSON objects and arrays, and containment checks.
