now that we are allowed to use C++23. we now have the luxury of using
`std::views::keys`.
in this change, we:
- replace `boost::adaptors::map_keys` with `std::views::keys`
- update affected code to work with `std::views::keys`
to reduce the dependency to boost for better maintainability, and
leverage standard library features for better long-term support.
this change is part of our ongoing effort to modernize our codebase
and reduce external dependencies where possible.

Currently, node ops virtual task gathers its children from all nodes contained
in a sum of service::topology::normal_nodes and service::topology::transition_nodes.
The maps may contain nodes that are down but weren't removed yet. So, if a user
requests the status of a node ops virtual task, the task's attempt to retrieve
its children list may fail with seastar::rpc::closed_error.
Filter out the tasks that are down in node_ops::task_manager_module::get_nodes.
Fixes: #20843.

Currently, node ops tasks type is retrieved from topology_request
without any change. Use respective node operation name instead.

system_keyspace::get_topology_request_entries returns entries for
requests which are running or have finished after specified time.
In task manager node ops task set the time so that they are shown
for task_ttl seconds after they have finished.
Add topology_tasks test suite for testing task manager's node ops
tasks. Add TaskManagerClient to topology_tasks for an easy usage
of task manager rest api.
Write a test for bootstrap, replace, rebuild, decommission and remove
top level tasks using the above.
