[Feature]: New-AzStorageBlobSASToken New-AzStorageAccountSASToken etc should support -AsSecureString

[NaridaL]

Description of the new feature

I'm creating a SAS url with New-AzStorageBlobSASToken and writing it to an AKV using Set-AzKeyVaultSecret.

Set-AzKeyVaultSecret expects a securestring, and when it doesn't get one, PowerShell is helpful and prints out the whole value. :-)

The New-AzStorage*SASToken powershell cmdlets should support an -AsSecureString parameter, which changes the return value to a secure string, similar to how Get-AzAccessToken handles it.

Proposed implementation details (optional)
