function Get-VSATenantRoletypeFunclist {
    <#
    .Synopsis
       Returns an array of funclist entries.
    .DESCRIPTION
       Returns an array of funclist entries for a specified roletype id OR for each roletype.
       Takes either Tenant or non-Tenant connection information.
    .PARAMETER VSAConnection
        Specifies existing non-Tenant VSAConnection.
    .PARAMETER URISuffix
        Specifies URI suffix if it differs from the default.
    .PARAMETER RoleTypeId
        Specifies roletype id to return an array of funclist entries.
    .PARAMETER Filter
        Specifies an OData $filter expression applied by the server.
    .PARAMETER Sort
        Specifies an OData $orderby expression applied by the server.
    .PARAMETER Parallel
        Fetches the remaining pages of a large collection concurrently instead of one after another.
        Opt-in: without it, behaviour is unchanged. Results are identical either way (same records,
        merged in $skip order). Only engages once the collection is large enough to be worth it
        (see -ParallelThreshold).
    .PARAMETER ThrottleLimit
        Maximum number of concurrent requests when -Parallel is used (default 8). On shared SaaS you
        are one tenant among many, so a modest value is a good citizen; the engine also reduces
        concurrency automatically if the server returns HTTP 429, then recovers.
    .PARAMETER ParallelThreshold
        Minimum total record count before -Parallel actually engages. 0 (default) means automatic:
        two full throttle windows, i.e. 2 * ThrottleLimit * 100 records. Below that the sequential
        path is used, because it is faster than paying to set up extra connections. .EXAMPLE
       Get-VSATenantRoletypeFunclist -RoleTypeId 4
    .INPUTS
       Accepts piped non-Tenant VSAConnection
    .OUTPUTS
       Array of funclist entries.
