function BuildE2ETestImage {
    <#
    .SYNOPSIS
        Re-builds base images for azure functions (based on images from https://github.com/Azure/azure-functions-docker)
    .DESCRIPTION
        Re-builds base images for azure functions. On the docker image created, the sample functions can then be copied and run. Can be used for End-To-End tests for all multilang samples.
    .NOTES
        On visual studio, the function can be built by opening the file and using the F8 key
    .EXAMPLE
        To build the node sample use the following : 
            BuildE2ETestImage 
        Extension bundle path is an optional parameter can be used. This is handy if the extension bundle has to be built locally and a custom extension is created for the first time and not available on the bundle.
        Refer : https://github.com/Azure/azure-functions-extension-bundles  on how to build the bundle on Linux/Windows
