PDI-1667: Implement Changes for CLI Version alpha.2

[erikostien-pingidentity]

• Add desciptions to each cobra command in the command tree.
• Remove "Warn" field from output command struct, in favor of using "Result" and "Message" fields to handle output coloring.
• Add warning for unspecified export environment ID.
• Add API client configuration values to error message upon client initialization failure. Include worker app secret only in TRACE or DEBUG mode.
• Update CLI version to match github release version
• Upon error in any RunE method, silence cobra error output in favor of allowing the output package in main.go to handle error output.
• Lower severity of failed pingone application secret export to warning, and continue exporting the rest of the secret resources.
