Set/Add/New secret should be separate cmdlets #218

Summary of the new feature / enhancement

The use of 'Set' instead of 'New' for the verb to create a secret doesn't seem intuitive to me, at least in the context of the descriptions provided by Get-Verb.

'New' creates a resource,
'Add' Adds a resource to a container or attaches an item to another item.
'Set' replaces data or creates a resource.

It seems to me that 'Set-Secret' here is combining all three verbs under the aegis of one verb.

If it were me, I'd look for the following.
'New-Secret' to create the secret,
'Add-Secret' to add it to the store.
'Set-Secret' to alter an existing secret.

These would make more sense to me than having a single cmdlet to do all three. 'Add-Secret' also auto-implies a 'Remove-Secret' and vice versa.
