* Improve transaction submission Before this pr the transaction pool validated each transaction, even if the transaction was already known to the pool. This pr changes the behavior to first check if we are already aware of a transaction and thus, to only validate them if we don't know them yet. However, there is still the possibility that a given transaction is validated multiple times. This can happen if the transaction is added the first time, but is not yet validated and added to the validated pool. Besides that, this pr fixes the wrong metrics of gossiped transactions in the network. It also moves some metrics to the transaction pool api, to better track when a transaction actually is scheduled for validation. * Make sure we don't submit the same transaction twice from the network concurrently * Remove added listener call * Feedback * Ignore banned on resubmit

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
