(kv) secret's value can be of any type, but safe forces string

[maxenced]

As per

safe/vault/secret.go

Line 21 in 9fdb79a

data map[string]string

, it seems a secret can only has string value. However, as described here : https://developer.hashicorp.com/vault/docs/secrets/kv/kv-v2

Key names must always be strings. If you write non-string values directly via the CLI, they will be converted into strings. > However, you can preserve non-string values by writing the key/value pairs to Vault from a JSON file or using the HTTP API.

Right now, safe import fails if you give anything but a string, with, for ex :
!! json: cannot unmarshal bool into Go value of type string
