[BUG] flytekit should support the flytectl config.yaml "admin.clientSecretEnvVar" option

[cosmicBboy]

Describe the bug

For context, pyflyte run and pyflyte register use the flytectl config.yaml file for various configuration settings, including client credential secret. The purpose of this issue is to support the clientSecretEnvVar key, which reads the credential from the specified environment variable.

admin:
  endpoint: dns:///<your-org.hosted.unionai.cloud>
  clientId: <client-id-from-app-creation>
  # If the secret will be mounted as a file:
  clientSecretLocation: /home/.../<ci-secret>
  # Or, if the secret will be mounted as an environment variable
  clientSecretEnvVar: <env-var>
logger:
  # Logger settings to control logger output. Useful to debug logger:
  show-source: true
  level: 1

Currently, flytekit supports the clientSecretLocation key, but not the clientSecretEnvVar: https://github.com/flyteorg/flytekit/blob/master/flytekit/configuration/__init__.py#L401-L411

Steps:

• Support reading admin.clientSecretEnvVar into the platform config
• If clientSecretLocation or clientSecretEnvVar is set, automatically set auth_mode to clientSecret (this is so we match the UnionCloud behavior, see here)

Expected behavior

client-secret-based authentication should work with admin.clientSecretEnvVar in the flytectl config.yaml
