Configuring cipher text for TACACS+ key

To improve security, when entering a TACACS+ key, the key is displayed in CIPHER text. When the feature is active, a masking of plaintext keys is supported using the CIPHER key (*) for configuration commands where sensitive information is entered. Show commands are shown in plaintext.

Enabling the CLI command hide-sensitive-data supports the masking of the sensitive information. This command is disabled by default.
