[DDW-257] Set up Shelley cardano-node selfnode environment

[nikolaglumac]

This PR sets up Shelley cardano-node selfnode environment.

Todos

• Fix selfnode test data path passing
• Fix default SMASH URL for selfnode
• Fix cardano-node PID and process-name handling
• Remove unnecessary cardano-wallet files
• Add exit cluster confirmation dialog
• Update wallet import scripts
• Add metadata registry server
• Add documentation (list of funded wallet recovery phrases: https://github.com/input-output-hk/cardano-wallet/blob/master/lib/core-integration/src/Test/Integration/Faucet.hs)
• Add KEEP_LOCAL_CLUSTER_RUNNING environment variable
• Expose eras info on getNetworkParameters Api endpoint response

Selfnode

1. Run yarn nix:selfnode from daedalus.

2. Run yarn dev from the subsequent nix-shell (use KEEP_LOCAL_CLUSTER_RUNNING environment variable to keep the local cluster running after Daedalus exits: KEEP_LOCAL_CLUSTER_RUNNING=true yarn dev)

3. Once Daedalus has started and has gotten past the loading screen run the following commands from a new terminal window if you wish to import funded wallets:

   • Byron wallets: yarn byron:wallet:importer
   • Shelley wallets: yarn shelley:wallet:importer
   • Mary wallets: yarn mary:wallet:importer (all of which contain native tokens which are visible once selfnode enters Mary era)
   • Yoroi Byron wallets: yarn yoroi:wallet:importer
   • ITN Byron wallets: yarn itn:byron:wallet:importer [Deprecated]
   • ITN Shelley wallets: yarn itn:shelley:wallet:importer [Deprecated]

   These scripts import 3 wallets by default. You can import up to 10 wallets by supplying WALLET_COUNT environment variable (e.g. WALLET_COUNT=10 yarn mary:wallet:importer).

   List of all funded wallet recovery phrases can be found here: https://github.com/input-output-hk/daedalus/blob/shelley-test-cluster/utils/api-importer/mnemonics.js

Notes:

• Cardano wallet process ID shown on the "Diagnostics" screen is faked and expected to match the Cardano node process ID.
• Stake pool metadata is fetched directly by default (IOHK SMASH server option is not available).
• Token metadata is fetched from a mock token metadata server which is automatically ran alongside the local cluster (there is no need to run it manually)
• Daedalus will ask you if you wish to keep the local cluster running after it exits - this option is useful if you need to preserve local cluster state between Daedalus restarts.

Parameter	Value
slotLength	0.2 sec
epochLength	50 slots
desiredPoolNumber	3
minimumUtxoValue	1 ADA

Testing Checklist

• Slack QA thread
• Make sure you are able to run the selfnode locally and import all types of wallets using the wallet-importer scripts
• Try basic wallet operations such as tx-features/delegation-features/native-tokens

@aleksandardjordjeviciohk @tomislavhoracek @yakovkaravelov @daniloprates @DominikGuzei we need to always convert quantities to string before passing them to BigNumber. This is a protection from JS number overflow. I have observed a lot of failures due to this happening in the selfnode environment.
