   CREATED BY: Vadim Melamed, EMAIL: vpasmodule@gmail.com
.DESCRIPTION
   USE THIS FUNCTION TO GET ALL THE AUTHENTICATION METHODS FOR A SPECIFIED APPLICATION ID
.LINK
   https://vpasmodule.com/commands/Get-VPASApplicationAuthentications
.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 AppID
   Unique ApplicationID (or Application Name) that will be used by the credential provider(s) to retrieve credentials
.PARAMETER InputParameters
   HashTable of values containing the parameters required to make the API call
.EXAMPLE
   $ApplicationAuthenticationsJSON = Get-VPASApplicationAuthentications -AppID {APPID VALUE}
.EXAMPLE
   $InputParameters = @{
        AppID = "TargetApplicationID"
   }
   $ApplicationAuthenticationsJSON = Get-VPASApplicationAuthentications -InputParameters $InputParameters
