Inserts a secret under the provided scope with the given name. If a secret
already exists with the same name, this command overwrites the existing
secret's value. The server encrypts the secret using the secret scope's
encryption settings before storing it.
You must have WRITE or MANAGE permission on the secret scope. The secret
key must consist of alphanumeric characters, dashes, underscores, and periods,
and cannot exceed 128 characters. The maximum allowed secret value size is 128
KB. The maximum number of secrets in a given scope is 1000.
The arguments "string-value" or "bytes-value" specify the type of the secret,
which will determine the value returned when the secret value is requested.
You can specify the secret value in one of three ways:
* Specify the value as a string using the --string-value flag.
* Input the secret when prompted interactively (single-line secrets).
* Pass the secret via standard input (multi-line secrets).
