Original Pull Request: https://github.com/netbirdio/netbird/pull/3818

State: closed
Merged: Yes

Describe your changes

Add an option to the management proto to enable or disable the lazy connection feature on the peer side. Command-line options and environment variables override the management configuration.

When the feature is enabled: Start the lazy connection manager and add all peers to the manager in the "active" st-ate.
When the feature is disabled: Stop the lazy connection manager and establish connections to all peers in the store.

Fix deadlock

The conn_mgr is protected by a mutex. However, because some internal functions are called via callbacks from the lazy connection manager, a deadlock can occur. The solution is to completely eliminate the callbacks.

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
