Torswitch context not to overlap with normal for better privacy

Is your feature request related to a problem? Please describe.
When both normal switch and torswitch coexist, its possible that normal switch overtakes all the peers in the attestation topic leaving nothing for torswitch. That can cause attestation to fail when torswitch tries to send. The reason is that torswitch is using the same mechanism for findling subnets, discovery and peerpool that normal has.

Describe the solution you'd like
Separate all the discovery, peerpool, connection quues from those of normal switch.
Make tor discovery a bit more frequent than normal.
