Fixes rancher#221 Add support for OpenSSH private key format for Git SSH authentication. * Update `createAuthFromOpts` function in `internal/cmd/cli/gitcloner/cloner.go` to handle OpenSSH private keys. * Add logic to read and parse OpenSSH private keys in `createAuthFromOpts` function. * Add support for known hosts file handling in `createAuthFromOpts` function. * Add fallback to insecure host key callback if known hosts file is not provided. * Add logic to handle username and password authentication in `createAuthFromOpts` function. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/rancher/fleet/issues/221?shareId=XXXX-XXXX-XXXX-XXXX).
* Update `GitCloner` struct to include `OAuthToken` field * Update `NewCmd` function to support OAuth token authentication * Add `TestArgsAreSetWithOAuthToken` test case to verify OAuth token handling

Why retry the exact same operation as the one that has just failed?

Same remark as in cloner.go: Why retry the exact same operation as the one that has just failed?
