Remove "create-genesis-json" startup option from witness_node

[abitmore]

User Story
@pmconrad mentioned in #1529 (comment):

... the --create-example-genesis option does not serve a useful purpose.
Things could be simplified by creating an example genesis file somewhere in the documentation, removing that option from the code...

Lately @jmjatlanta implemented the code in commit 46e248e, so the option will be removed if #1529 is merged. Then we need to update related documents and tutorials.

This issue is for tracking documentation work and potential related discussions.

I modified the wiki page for private testnet here: https://github.com/bitshares/bitshares-core/wiki/private-testnet

@cedar-book I guess you're aware of where other related docs are? Please take a look. Thanks.

@jmjatlanta please be aware that the private keys for the genesis.json file in testnet branch are not publicly known. For new private testnets, people need to put keys controlled by themselves into genesis.json (like the "create-genesis-file" option did). Current instruction in wiki is not clear enough for newcomers.

A publicly known key pair is:

• public key: BTS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
• private key: 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

Other publicly known private keys can be found in https://github.com/bitshares/bitshares-core/blob/6e11c31d40a8e63f52402887860349d9f96d883b/testnet-shared-private-keys.txt which I guess are paired with the public keys in the end of https://github.com/bitshares/bitshares-core/blob/6e11c31d40a8e63f52402887860349d9f96d883b/testnet-shared-accounts.txt. These files among some other old files have been removed in PR #1533.

By the way, people can use the suggest-brain-key option in cli_wallet to generate new keys pairs. It's introduced in version 2.0.180823 by PR #1039. There may be docs for this, I guess we can link the docs together.

@abitmore, yes, I am planing to renew the testnets section (the dev website).

Outside the wallet private keys can also be generated with ./get_dev_key --help using the corresponding network prefix("BTS", "TEST", "MY", etc). The public key generated need to go into the private testnet genesis file for active and owner keys of all the "initX" accounts and also to "nathan" Then the public/private key pair is added into the blockchain config.

[cedar-book]

@oxarbitrage, Thank you for the information! I'll add that how to information.

@jmjatlanta I am setup my dex using Bitshares Core but facing an error while running on lnix. when I run with new chain with zero block process not initiate.

@reactivespace If you believe that the removal of create-genesis-json is the problem, please post more details of the message you are receiving. For technical assistance, you may try https://bitsharestalk.org.

[cedar-book]

Updated to remove 'create-genesis-json' command line section - Private Testnet.
To share the Private Testnet Genesis file information, created new page for.

[cedar-book]

Updated: private testnet - Genesis file section

• added notes to mention about the above two discussions.
