(Feat) Cosmos chain base

[webston]

Before submitting this PR, please make sure:

• Your code builds clean without any errors or warnings
• You are using approved title ("feat/", "fix/", "docs/", "refactor/")

A description of the changes proposed in the pull request:

• Adds a Cosmos chain base that can be used to add Cosmos-based chains and connectors. We are currently developing a Sifchain connector and use this base to add Sifchain as a chain and connector.
• Removes a Solana address param from test.base.ts because it sends a Solana address with each request even if it is used for other chains.
• Adds support for running tests when server.unsafeDevModeWithHTTP is true.

Tests performed by the developer:

• Manually sent HTTP requests to all /cosmos and /wallet routes
• Ran automated tests with jest

Tips for QA testing:

• Add a cosmos wallet through the /wallet endpoint
• Send a POST request to /cosmos/balances to get the balance of an added wallet
• Send a POST request to /cosmos/poll with a txHash to get a transaction
• Run jest tests

Hi @nikspz, I solved the conflicts.

The Gateway build + unit tests workflow seems to be failing because of this - no such file or directory, open '/usr/src/app/certs/ca_cert.pem'. Do you know why it happens?

[nikspz]

@webston Could you please fix Failing test?

[webston]

@nikspz The tests were failing because the SSL certs couldn't be found. I saw some updates related to the SSL certs in the development branch, so I merged with it. Can you please run the workflow to see if the issue is solved?

[webston]

I think I found the issue and pushed a fix. Can you please run the workflow again?

[webston]

I solved issues related to the RPC, which were failing the workflow tests, and merged with the latest development branch.

[rapcmia]

LGTM

[webston]

All tests are passing when I run the workflow in a private repo. @rapcmia can you please trigger a new attempt for the checks?

[Faouzijedidi1]

LGTM!
