    .SYNOPSIS
        Disables SSL certificate validation
    .DESCRIPTION
        Disable-SSLValidation disables SSL certificate validation by using reflection to implement the System.Net.ICertificatePolicy class.
        Author: Matthew Graeber (@mattifestation)
        License: BSD 3-Clause
    .NOTES
        Reflection is ideal in situations when a script executes in an environment in which you cannot call csc.ese to compile source code.
        If compiling code is an option, then implementing System.Net.ICertificatePolicy in C# and Add-Type is trivial.
