Create a Python analytics SDK

[PSalant726]

The SDK should implement a "managed API" interface for Python applications that wish to send analytics events to the API server. It should enable applications to:

• Create an AnalyticsClient instance, which enables caller-specific configuration, such as API keys, UUID, etc.
• Create an AnalyticsEvent instance, which validates attributes for presence and content, as necessary
• Abstract away the details of sending a POST request to the API server's /events endpoint
• Identify and handle errors

The SDK should not create any log entries. Include usage and reference documentation in a README.md file.

Usage may be as simple as:

from logging import getLogger
from os import getenv
from fideslog.sdk.python import (
	AnalyticsClient,
	AnalyticsError,
	AnalyticsEvent,
	FIDESCTL_CLI,
	get_or_create_uuid,
)
	
logger = getLogger(__name__)
client = AnalyticsClient(getenv("FIDESLOG_API_KEY"), get_or_create_uuid(), FIDESCTL_CLI)
event = AnalyticsEvent("event type", "command name", ...)

try:
	client.send(event)
except AnalyticsError as e:
	logger.warn("failed to send analytics event: %s", e["message"])
except:
	logger.warn("something else has gone wrong")
else:
	logger.info("analytics event sent")
