This patch is a part of vector_store_client sharded service
implementation for a communication with vector-store service.
There is a need for abortable sequention_producer operator(). The
existing operator() is changed to allow timeout argument with default
time_point::max() (as current default usage) and the new operator() is
created with abort_source parameter.

This PR extends authentication with 2 mechanisms:
- a new role_manager subclass, which allows managing users via
LDAP server,
- a new authenticator, which delegates plaintext authentication
to a running saslauthd daemon.
The features have been ported from the enterprise repository
with their test.py tests and the documentation as part of
changing license to source available.
