Feature: Add aca-py command line option --genesis-file

[SmithSamuelM]

The current aca-py has two methods for injecting the genesis transactions.

1. --genesis-transactions
2. --genesis-url

The first is not a great user experience. The genesis transactions are a newline separated list of JSON data structures; not event a JSON list. This requires escaping to get the transactions to correctly input from a command line shell. A minimal four node set of genesis transactions are still almost 3K Characters.So this is not a reasonable option.

The second option genesis url requires some web server that provides the genesis transactions. This is a reasonable approach from a user experience but does have a hard dependency on a web server.

A practical alternative that has both decent user experience and no external dependencies is to allow a local file path input to provide the genesis transactions.

Agree that is a reasonable approach - I thought that was an option.

Can this be used as a temporary workaround? --genesis-transactions "$(cat <genesis-file>)"

I can't find it as an option anywhere so it would be good to add. Thanks. Also good suggestion for workaround.
