[DRAFT] Node release 10.6.0 integration

[ana-pantilie]

Needs #1525

[jasagredo]

Just FYI, #1525 only does the minimal integration for the ledger to compile. It doesn't add anything related to the intra-era HF or the new era.

Also it depends on a temporary fork from ouroboros-network, and instead a newer network will have to be released and integrated

That may explain why I was having trouble getting this to build! Thanks.
