[Feature]: Get-AzKeyVaultSecret should allow to fetch by ID

[ishepherd]

Description of the new feature

Because Key Vault secrets have a global unique ID and it's just a URL.

We tend to paste that URL around the place, e.g. in app configuration. It would be convenient if the Get-AzKeyVaultSecret supported those URLs.

What I'd like to do

Get-AzKeyVaultSecret -Id https://myvault.vault.azure.net/secrets/MySecret
Get-AzKeyVaultSecret -Id https://myvault.vault.azure.net/secrets/MySecret/03d6fd62056a4790a8982b1a75f320f8

Alternatives

• Helper class. The .NET client provides KeyVaultSecretIdentifier
• Do it manually ... Kinda ugly:

$token = Get-AzAccessToken -ResourceUrl https://vault.azure.net
$headers = @{"Authorization" = "Bearer $($token.Token)"}
$response = Invoke-RestMethod -Uri https://myvault.vault.azure.net/secrets/MySecret/03d6fd62056a4790a8982b1a75f320f8?api-version=7.1 -Headers $headers

Proposed implementation details (optional)

No response
