storcon: use https safekeeper api (#11065)

## Problem

Storage controller uses http for requests to safekeeper management API.

Closes: https://github.com/neondatabase/cloud/issues/24835

## Summary of changes
- Add `use_https_safekeeper_api` option to storcon to use https api
- Use https for requests to safekeeper management API if this option is
enabled
- Add `ssl_ca_file` option to storcon for ability to specify custom root
CA certificate
