    Adding spec for supporting multiple secret store backends
    
    Updated patch to clarify review comments and correct typos.
    Added details around plugin name and how its used in secret_stores
    'name' field.
    
    Added changes related to how multiple plugin configuration is going to
    be specified and used.
    
    Added field to capture crypto_plugin name in addition to secret store plugin
    name. This is done as both software only and pkcs11 plugin uses database
    (store_crypto) as storage backend. Difference is in crypto plugin used
    (simple crypto vs p11_crypto).
