fix(p2p): implement retry mechanism for `Head` request

Head method should have its default timeout for all requests(if it wasn't set) and in case we receive less than 3/4 of a positive response, we should ask more peers to determine the current Head.
Note: we should implement retry only for tracked peers. For the trusted peers - only timeout will be enough.

Start by locating the Head method and the code handling request timeouts, tracked peers, trusted peers, and peer responses. Verify how positive responses are counted; the work is done when Head applies a default timeout, retries with additional tracked peers below the stated response threshold, and does not retry trusted peers.
