Great content, @wojcik91. Are you planning to finish this PR?

[wojcik91]

@ipopescu I apologize for the delay, I must have missed some notifications. The stuff you pointed out is now fixed.

@wojcik91, thank you for the updates. Could you please also change all deploys to transactions, including the casper-client command, which should use put-transaction? Please also test it.

Since deploy is deprecated, we are updating all 2.0 documentation to use transaction instead of deploy.

@ipopescu I removed all references to deploys, but I still have one outstanding issue - the new put-txn command is in reality not a 1:1 translation of put-deploy.
I did actually use it to deploy a contract on devnet, but I did not figure out a way to correctly call installed contracts without using WASM code yet. Does some documentation for this command exist already?

Thanks, @wojcik91. This PR is ready for merging. We are still working on documentation for 2.0, including calling contracts. Let's merge this content and come back to the casper-client command once the docs for calling contracts are available.
