feat(lib/parachain): added parachain service and registering protocols

[kishansagathiya]

Changes

• Adds parachain service
• registers collator and validation protocol
• confirms that we can communicate with collators by talking to them in run() function

Tests

Run a gossamer node, a polkadot and a collator node (adder test parachain from polkadot). I think you would be able to test it will just gossamer node and a collator node as well.

Observe the logs and notice that you can

• register collation and validation protocol
• negotiate a handshake and establish connection between gossamer and collator
• send data to collator and receive data from collator

Run polkadot node and gossamer node

• I generally clean my setup first

rm -r /tmp/alice /tmp/bob /tmp/charlie /tmp/dave ~/.gossamer /home/kishan/.local/share/polkadot/
./bin/gossamer init --force --chain westend-local

• Run polkadot node

./polkadot --bob  --listen-addr /ip4/0.0.0.0/tcp/30334 --validator --base-path /tmp/bob --ws-port 8556 --rpc-port 8555 --chain /home/kishan/code/gossamer/chain/westend-local/westend-local-spec-raw.json --log=trace &>  ~/code/gossamer/bob_trace.log

Look for identity in the logs an pick up peer id of this node

• Run gossamer node

./bin/gossamer --chain westend-local --key alice --bootnodes /ip4/127.0.0.1/tcp/30334/p2p/<peer id of bob retrieved from above> --log global=trace >  ~/code/gossamer/alice_trace.log

Run adder parachain

• cd into polkadot repo.
• Build adder parachain

cargo build --release -p test-parachain-adder-collator

• Run a collator node from adder test parachain

target/release/adder-collator --chain /home/kishan/code/gossamer/chain/westend-local/westend-local-spec-raw.json --tmp --port 50553 --rpc-port 9933 --ws-port 9944 --prometheus-port 9615 --rpc-cors all --log=trace &> ~/code/gossamer/parachain.log

go test -tags integration github.com/ChainSafe/gossamer
