x-wf opened a new issue #1321: SignatureDoesNotMatch for manual request
   ## Summary
   While attempting to perform a manual request, it appears to be an issue with the credentials
being used.
   ## Detailed Information
   Upon attempting to create EC2 Launch Template, by performing a manual request with the
EC2 driver, it's returning `libcloud.common.types.InvalidCredsError: 'SignatureDoesNotMatch`
   More specifically I have a function which I attempt to create a simple Launch Template
   ialize test
   def initialize_test():
       # authenticate
       aws = get_driver(Provider.EC2)
       driver = login_aws(aws)
       // Other actions that are used e.g. driver.ex_create_security_group works perfect
       // Manually performing requests isn't working
   def new_template(driver):
       params = {
           'Action': 'CreateLaunchTemplate',
           'LaunchTemplateName': "test-template",
           'LaunchTemplateData': {
               'ImageId': "ami-06b41651a26fbba09",
               'InstanceType': "t3.xlarge",
               'NetworkInterface': {
                   1: {
                       'AssociatePublicIpAddress': True
       // Breaks here
       response = driver.connection.request("/", params=params)
   And this throws
   libcloud.common.types.InvalidCredsError: 'SignatureDoesNotMatch: The request signature
we calculated does not match the signature you provided. Check your AWS Secret Access Key
and signing method. Consult the service documentation for details.'
   The project used is running python 3.7.4, using apache-libcloud 2.5.0.
