## Description
Instead of initializing static AWS credentials, we rely on the
credential provider chain in [Kopia](https://github.com/kopia/kopia/pull/2213) to discover and initialize credentials.
This currently supports the following in this order:
- Static credentials
- Environment variables (what Corso used to implement)
- IAM
Going forward, this will also allow us to support shared credentials (cred file) once that is
added to the credential provider chain.

Makes the necessary changes, including adding helper
funcs, to bring the CLI up to an integration-testable
state. The changes made in this commit should be
sufficient for most other CLI tests. Includes a single
test as verification.
The alias of testing to ctesting prevented auto-importing
of the testing library. This change (arbitrarily) renames
the package so that it doesn't collide with the core pkg
for "testing".
* allow connect to create .corso config file
Current bug: if no .corso config file exists, then repo connect
will always fail, even if it has the correct details to build
a new config file. Solution: allow connect to build a .corso
config file when missing, so long as the operation succeeds
otherwise.
In tandem, return an error whenever a user attempts to
call repo connect with details that do not match the existing
.corso config file.
* use config file for backup create
Now that corso stores its prior connection details in a config
file, that file should get used to retrieve storage details as needed.
Adds unit tests for the config file read/write helpers.
It also uncovered a bug in how viper handles writing a config file when a config file path is set
directly. This required a workaround in our init logic when we are using a custom config file name.
This commit does the following:
- Refactors the init logic into a InitConfig helper
- Adds a unit test to validate basic ReadRepoConfig behavior
- Adds a unit test that uses WriteReadConfig to write config and ReadRepoConfig to read it
