[feature] Built-in stratum server (pool)

[DeckerSU]

This issue is created for public testing new feature - built-in stratum pool. To test in you'll need build komodod from stratum-dev branch as usually, and launch it with stratum server specific keys:

Stratum server options:

  -stratum
       Enable stratum server (default: off)

  -stratumbind=<addr>
       Bind to given address to listen for Stratum work requests. Use
       [host]:port notation for IPv6. This option can be specified multiple
       times (default: bind to all interfaces)

  -stratumport=<port>
       Listen for Stratum work requests on <port> (default: 8771 or testnet:
       8771)

  -stratumallowip=<ip>
       Allow Stratum work requests from specified source. Valid for <ip> are a
       single IP (e.g. 1.2.3.4), a network/netmask (e.g. 1.2.3.4/255.255.255.0)
       or a network/CIDR (e.g. 1.2.3.4/24). This option can be specified
       multiple times

For example. to launch KMD with stratum pool on default (rpcPort + 1000) stratum port 8771, you'll need to execute:

./src/komodod -stratum &

And for launch DEX assetchain with stratum on port 10216:

./src/komodod -ac_name=DEX -ac_supply=999999 -addnode=95.213.238.98 -stratum -stratumport=10216 &

Then point your favorite miner or ASIC on stratum+tcp://stratum_ip:stratum_port. Don't forget to specify username as valid KMD address, like RDeckerSubnU8QVgrhj27apzUvbVK3pnTk and any password (x, for example).

Will appreciate for any comments in this topic from users tried new feature. Thx in advance!

p.s. If you'll found a block address you specified in miner will receive blockreward. For example, if you'll launch ccminer as:

./ccminer --algo=equihash --url=stratum+tcp://127.0.0.1:10216 --user=RDeckerSubnU8QVgrhj27apzUvbVK3pnTk --pass=x 

And it will found a block, address RDeckerSubnU8QVgrhj27apzUvbVK3pnTk will receive a reward.

MORTY example:

./komodod -ac_name=MORTY -ac_supply=90000000000 -ac_reward=100000000 -ac_cc=3 -ac_staked=10 -addnode=95.217.44.58 -addnode=138.201.136.145 -stratum

Stratum server will listen on rpc.63812 + 1000 port, so, stratum server port will be 64812.

Make sure that we have connections:

komodo-cli -ac_name=MORTY getinfo | jq .connections

And our latest block corresponding to explorer, i.e. chain is 100% synced.

Then start a miner:

./ccminer --algo=equihash --url=stratum+tcp://127.0.0.1:64812 --user=RDeckerSubnU8QVgrhj27apzUvbVK3pnTk --pass=x 

And after some time we will get a first block.
