Removed blacklist functionality from transaction pool

Removed blacklist functionality from transaction pool:

1. Removed blacklist and allowedTxs validation logic from the transaction pool
2. Updated node.New() signature by removing blacklist and allowedTxs parameters
3. Removed CLI flags and configuration fields related to blacklist functionality

We need to remove the allowed list as well, because they are going in pair with blacklist

we can't just remove it, because it has references from config migrations. I didn't check will it be ok to modify migrations, maybe it this case it will be ok
