Importing, displaying Vault settings, framework for Gets

This change set includes Importing vault settings and displaying the same and getting list of cloud services. Also framework for GETs is ready.

Import cmdlet allows piping, example usage is here:
PS C:\> $resourceName = "resourceName"
PS C:\> $cloudServiceName = "cloudServiceName"
	
PS C:\> Get-AzureSiteRecoveryVaultSettingFile -ResourceName $resourceName -CloudSeriveName $cloudServiceName | Import-AzureSiteRecoveryVaultSetting
Is Get-AzureCloudServices a cmdlet we want to ship? Does look like it belongs to us. Isn't there already a cmdlet that does this. 

If we want to have it, shouldn't it be with our name - like Get-AzureSiteRecoveryCloudServices...?
