Implemented GRPC client to query account sequence

[andynog]

Closes: cosmos/ibc-proto-rs#18

Description

This PR has the logic to start using the GRPC service from a Cosmos chain to retrieve account information. The account has the sequence number that is needed to submit a transaction. With this implementation there is no need anymore to manually query the account sequence in order to submit a transaction. Changes implemented:

• Added logic to proto_compiler to generate the GRPC client (using tonic
• Added logic to retrieve the GRPC address from the configuration file
• Added method to Cosmos chain to query_account that leverages the GRPC client
• Removed the old account sequence parameter from the tx raw command
• Updated instructions on Relayer CLI README to remove the account sequence instructions

---

For contributor use:

• Updated the Unreleased section of CHANGELOG.md with the issue.
• If applicable: Unit tests written, added test to CI.
• Linked to Github issue with discussion and accepted design OR link to spec that describes this work.
• Updated relevant documentation (docs/) and code comments.
• Re-reviewed Files changed in the Github PR explorer.

Just noticed there a lot of file changes but a lot of them are proto files that were updated and after including tonic seems it also formatted the files.

There might be an additional change required which is the cosmos address from the key_seed.json. Right now it has a hard coded address. I will look into this tomorrow.

LGTM but will defer to @ancazamfir for the final approbation. Great stuff @andynog!

[ancazamfir]

Looks good! Thanks Andy!!
Please update the changelog and pin the protos to sdk v0.40.0-rc0 (commit 15324920548c2629e51d837bcefc1cbc40797c5d)

@ancazamfir, I've merged #365 and there were a lot of merging conflicts that I've resolved to the best of my knowledge. Since there were not only changes related to the proto compiler but also for the tx commands maybe from other commits to master, I had to resolve these conflicts. The only weird thing is that if I run a conn-init tx like I've been testing, using the dev-env I cannot see the connection created and the output of the command is Success client updated: [ ]. So not sure something changed or it's something wrong with the merging.

Could you please test the txs with this branch and see if still makes sense for you ?

Here's what I've tested

cargo run --bin relayer -- -c ./relayer-cli/tests/fixtures/two_chains.toml tx raw conn-init ibc0 ibc1 ibczeroclient ibconeclient ibczeroconn246 -k key
_seed.json

and I get
