chore: add way to invoke cargo from go code in effort to reuse rust t…

…ests (#967)

* feat: use sim preamble to restore needed entries

Currently the test uses a sleep because it has been a struggle to get an entry's expiration

* Stop using a magic wait time and clean-up the code

* feat: run cargo tests from go

First example of using `cargo test` from the go code.

* feat: add all tests from hello_world tests

* fix: remove failing and overlapping tests

* chore: add wrap test to show contract is created successfully

* chore: remove comment

* feat: organize CLI tests so that they can be invoked programatically

* feat: use sim preamble to restore needed entries

Currently the test uses a sleep because it has been a struggle to get an entry's expiration

* Stop using a magic wait time and clean-up the code

* fix: remove extraneous test

Since other tests will deploy hello_world this adds nothing
