.Synopsis
   Cmdlet used to either get storage controllers, get virtual disks, get physical disks or reset the storage controller using Redfish API OEM extension.
.DESCRIPTION
   Cmdlet used to either get storage controllers, get virtual disks, get physical disks or reset the storage controller using Redfish API OEM extension.
   - idrac_ip: Pass in iDRAC IP address
   - idrac_username: Pass in iDRAC username
   - idrac_password: Pass in iDRAC username password
   - get_storage_controllers: Pass in "y" to get current storage controller FQDDs for the server. Pass in "yy" to get detailed information for each storage controller
   - get_virtual_disks: Pass in the controller FQDD to get current virtual disks. Example, pass in "RAID.Integrated.1-1" to get current virtual disks for integrated storage controller
   - get_virtual_disks_details: Pass in the virtual disk FQDD to get detailed VD information. Example, pass in "Disk.Virtual.0:RAID.Slot.6-1" to get detailed virtual disk information
   - reset_storage_controller: Pass in the controller FQDD. Example, pass in "RAID.Slot.6-1".
    
.EXAMPLE
    .\Invoke-StorageResetConfigREDFISH.ps1 -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -get_storage_controllers y
   This example will return storage controller FQDDs for the server.
.EXAMPLE
   .\Invoke-StorageResetConfigREDFISH.ps1 -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -reset_storage_controller RAID.Mezzanine.1-1
   This example will reset the storage controller RAID.Mezzanine.1-1
