   DELETE EPV USER
   CREATED BY: Vadim Melamed, EMAIL: vmelamed5@gmail.com
.DESCRIPTION
   USE THIS FUNCTION TO DELETE AN EPV USER
.PARAMETER token
   HashTable of data containing various pieces of login information (PVWA, LoginToken, HeaderType, etc).
   If -token is not passed, function will use last known hashtable generated by New-VPASToken
.PARAMETER LookupBy
   Which method will be used to query for the target EPVUser, via Username or UserID
   Possible values: Username, UserID
.PARAMETER LookupVal
   Target searchquery string
.PARAMETER Confirm
   Skip the confirmation prompt confirming the deletion/removal of an EPVUser
.PARAMETER WhatIf
   Run code simulation to see what is affected by running the command as well as any possible implications
   This is a code simulation flag, meaning the command will NOT actually run
.PARAMETER HideWhatIfOutput
   Suppress any code simulation output from the console
.EXAMPLE
   $WhatIfSimulation = Remove-VPASEPVUser -Username {USERNAME VALUE} -WhatIf
.EXAMPLE
   $DeleteEPVUserStatus = Remove-VPASEPVUser -Username {USERNAME VALUE}
.EXAMPLE
   $DeleteEPVUserStatus = Remove-VPASEPVUser -Username {USERNAME VALUE} -Confirm
.OUTPUTS
   $true if successful
   $false if failed
