   DELETE AUTHENTICATION METHOD
   CREATED BY: Vadim Melamed, EMAIL: vmelamed5@gmail.com
.DESCRIPTION
   USE THIS FUNCTION TO DELETE AUTHENTICATION METHOD INTO CYBERARK
.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 AuthMethodSearch
   Search string to find the target AuthenticationMethod
.PARAMETER AuthMethodID
   Unique ID that maps to the target AuthenticationMethod
   Supply AuthMethodID to skip any querying for target AuthenticationMethod
.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-VPASAuthenticationMethod -AuthMethodID {AUTH METHOD ID VALUE} -WhatIf
.EXAMPLE
   $DeleteAuthenticationMethodStatus = Remove-VPASAuthenticationMethod -AuthMethodID {AUTH METHOD ID VALUE}
.OUTPUTS
   $true if successful
   $false if failed
