[Feature] Statistics collection v2

[simonwicky]

Ticket

JIRA-NET-422

Description

This PR improves on the minimalistic statistics collection that already exists :

• CLI control to enable/disable collection
• CLI control to allow direct sending (not via the tunnel)
• CLI control over the seed for the stats ID, and it gets persisted
• Enabling/disabling collection doesn't require a daemon reboot
• Sessions data is more more comprehensive and accurate
• Sending strategy involves retries
  This PR requires Statistics API v2 nym#6227 to be merged in the core first, and a Cargo.lock update then

Side note

App toggle and tooltip might need to be updated. iOS still needs to have disabled stats

I have an upcoming change with a new v3 configuration in review at the moment (https://github.com/nymtech/nym-vpn-client/pull/4015/files). This includes a restructure of the service config into multiple modules. Can you please wait until that is merged before merging this change?

[simonwicky]

Monorepo PR was merged, Cargo.lock updated.
We're waiting for #4015 to be merged to avoid merge conflicts and for an update of the config following this.

Don't you need to convert it from persistent representation? cc @trojanfoe

    // - If the tunnel is connected in wireguard mode, it will go through wireguard
    // We thus need this option to allow users to report even if they can't connect (i.e. if they're being censored)
    /// Allow statistics sending, even if not conncetced to the mixnet/vpn

typo in connected
