Add support for remaining Tendermint RPC endpoints

[thanethomson]

We need to implement client support for the full set of Tendermint RPC endpoints. (Is it necessary to implement the unsafe methods too?)

What's the definition of "done" for this issue?

When we have RPC client support for the following additional endpoints:

• [x] /block_by_hash
• [ ] /dump_consensus_state
• [x] /consensus_params (#972)
• [ ] /unconfirmed_txs
• [ ] /num_unconfirmed_txs
• [x] /block_search (#991)
• [x] /tx (#863)
• [ ] /check_tx
• [x] /header (#1193)

Not sure why GitHub closed this issue.

In https://github.com/informalsystems/tendermint-rs/pull/991

Partially resolves #832.

The little robots look for certain keywords, resovles is one of them.

The little robots are pretty dumb, because they missed the most important word in that sentence :smile:

@thanethomson I made a PR that addresses the block_by_hash RPC endpoint: #1089. How can I get started on a review?

[hansl]

Is there any update on this? After the yanking of TM 0.35 a lot of these endpoints were removed from the latest TM-rs 0.25 release.

@thanethomson /block_by_hash can be re-added with https://github.com/informalsystems/tendermint-rs/pull/1206 but it needs a reviewer.

@mzabaluev Can you please take a look at this and update the issue accordingly to the changes introduced in #1193?

[mzabaluev]

Thanks for the heads-up @romac, I have updated the check boxes accordingly to what is present in #1193. block_by_hash has already been implemented earlier.
