do subnet discoveries until we have MESH_N_LOW many peers (#1886)

Browse Source 
## Issue Addressed

NA

## Proposed Changes

Increases the target peers for a subnet, so that subnet queries are executed until we have at least the minimum required peers for a mesh (`MESH_N_LOW`). We keep the limit of `6` target peers for aggregated subnet discovery queries, therefore the size (and the time needed) for a query doesn't change.
