[SecretManagement] Name inconsistencies

[itfranck]

Cmdlets referring to the same thing have different parameter names

For instance,

Using Vault
Get-Secret, Get-SecretInfo, Set-Secret, Test-SecretVault, Remove-Secret

Using Name
Unregister-SecretVault, Test-SecretVault, Get-SecretVault

Both Vault and Name reference vaults names.
Name also reference secret names on other cmdlet.

Proposed technical implementation details (optional)

In my opinion, Az.Keyvault have it right. All their cmdlet use:

VaultName : Reference to vault name
Name : Reference to secret name

For consistency sake,
I would think that SecretManagement would benefit from this simple change before leaving prerelease.
