Add AWSCloud plugin

[VigneshSP94]

I believe this project is all about monitoring cloud platforms, so why not add support for AWS. AWS has a robust API package boto3. Below is a snip, I will be glad to take this up if I can get the project and contribution details.

class Aws:

    def __init__(self, aws_key, aws_id, aws_reg, end_pt_url):
        self.aws_key = aws_key
        self.aws_id = aws_id
        self.aws_reg = aws_reg
        self.end_pt_url = end_pt_url

    def session_to_aws(self):
        # this gets the instances from the given aws account.
        vpcc = boto3.session.Session()
        return vpcc.resource(service_name='ec2', use_ssl=True, verify=False, aws_access_key_id=self.aws_id,
                             aws_secret_access_key=self.aws_key,
                             region_name=self.aws_reg, endpoint_url=self.end_pt_url)`

This can grab the instance, SG and all other stuff. Then we can work on serializing the data and send it to the appropriate indexing engine.
