feat(persistence-fabric): add sample setup scripts, improve documenta…
…tion
- Fix error when empty `transaction.actions` was received from a block.
- Copy schema SQL during build.
- Remove unique constraint on fabric transactions hash column (there
are transactions with empty hash that would break it).
- Improve parsing of certificate subject/issuer attributes to handle more
delimiters.
- Use new `install-fabric.sh` script (that is recommended for Fabric 2.5)
instead of old bootstrap to fix some runtime issues that I've encountered.
- Add sample setup scripts. Simple can be used to run persistence against
already running fabric ledger, complete will setup entire environment
and run some basic operations to generate sample data.
- Improve documentation to include these new scripts and how to use them, fix
smaller issues.
