Enable runtime updates of vector_store_uri configuration without
requiring server restart.
This allows to dynamically enable, disable, or switch the vector search node endpoint on the fly.
Introduce lightweight wrapper for seastar::http::experimental::client
This wrapper simplifies request creation by automatically injecting the host name.
As requested in #22102, #22103 and #22105 moved the files and fixed other includes and build system.
Moved files:
- clustering_bounds_comparator.hh
- keys.cc
- keys.hh
- clustering_interval_set.hh
- clustering_key_filter.hh
- clustering_ranges_walker.hh
- compound_compat.hh
- compound.hh
- full_position.hh

This patch is a part of vector_store_client sharded service
implementation for a communication with vector-store service.
It implements a functionality for ANN search request to a vector-store
service. It sends request, receive response and after parsing it returns
the list of primary keys.
It adds json parsing functionality specific for the HTTP ANN API.
It adds a hardcoded http request timeout for retrieving response from
the Vector Store service.
It also adds an automatic boost test of the ANN search interface, which
uses a mockup http server in a background to simulate vector-store
service.
It adds a documentation for HTTP API protocol used used for ANN
functionality.
Fixes: VS-47
This patch is a part of vector_store_client sharded service
implementation for a communication with vector-store service.
It implements functionality for refreshing ip address of the
vector-store service dns name and creating a new HTTP client with that
address. It also provides cleanup of unused http clients. There are
hardcoded intervals for dns refresh and old http clients cleanup, and
timeout for requesting new http client.
This patch introduces two background tasks - for dns resolving
task and for cleanup old http clients.
It adds unit tests for possible dns refreshing issues.

This patch is a part of vector_store_client sharded service
implementation for a communication with vector-store service.
It adds a `services/vector_store_client.{cc|hh}` sharded service and a
configuration parameter `vector_store_uri` with a
`http://vector-store.dns.name:port` format. If there will be an error
during parsing that parameter there will be an exception during
construction.
For the future unit testing purposes the patch adds
`vector_store_client_tester` as a way to inject mockup functionality.
This service will be used by the select statements for the Vector search
indexes (see VS-46). For this reason I've added vector_store_client
service in the query processor.
