Function init_hq_server

crates/hyperqueue/src/server/bootstrap.rs:62–77

This function initializes the HQ server. It takes a path to a directory and tries to find metadata of a running HQ server either directly inside the directory or in a path linked to by a symlink named [`SYMLINK_PATH`]. If no metadata is found or the metadata links to a server that seems to be offline, a new server will be started. If an already running server is found, an error will be returned
