proc CopyFileFromLinuxApiServer {args} {
    # Description
    #    Using REST API to copy files from a Linux API server to local filesystem.
    # 
    # Requirements
    #     IxNetwork 8.50+ because the package IxTclNetwork comes with http, tls and json
    #     that this proc needs. Otherwise, you need to install http, tls and json.
    #
    # Parameters
    #    -apiServerIp:   The Linux API server IP address
    #    -sessionId:     The session ID number
    #    -apiKey:        The unique user account api-key
    #    -pathExtension: All files are located in a predefined path in the Linux API server.
    #                    In some situation like packet capturing, the captured file is located.
    #                    in deeper subdirectories.  Provide the extended subdirectory without the file name.
    #                    You need to include the forward slash.
    #                    For example: /captures/packetCapture
    #    -srcFile:       The filename to copy from the Linux API server.
    #    -dstFilePath:   The path+filename in the local filesystem where you want to copy the file to.
    # 
    # Example:
    #
    #    package require http
    #    package require json
    #    package require tls
    #    ::http::register https 443 ::tls::socket
    #
    #    # Example: In Quick Test, use api to get the $resultPath and pass it in with the -linuxSrcFilePath parameter.
    #    #          This method applies to other tests where there should be an api to get the $resultPath.
    #    CopyFileFromLinuxApiServer \
    #       -apiServerIp $apiServerIp \
    #       -sessionId 5 \
    #       -apiKey $apiKey \
    #       -linuxSrcFilePath $resultPath \
    #       -srcFile logFile.txt \
    #       -dstFilePath ./qtLogFile.txt
    #  
    #    # Example with pathExtension for packet capture
    #    copyFileFromLinuxApiServer \
    #        -apiServerIp $linuxApiServerIp \
    #        -sessionId 7 \
    #        -apiKey e5d16d3258014241872990301abc \
