Potential re-named sdelete usage (ASIM Version)

Description

'This detection looks for command line parameters associated with the use of Sysinternals sdelete (https://docs.microsoft.com/sysinternals/downloads/sdelete) to delete multiple files on a host's C drive. A threat actor may re-name the tool to avoid detection and then use it for destructive attacks on a host. This detection uses the ASIM imProcess parser, this will need to be deployed before use - https://docs.microsoft.com/azure/sentinel/normalization'
