paws.common-v0.8.0

Features:

• migrate backend from httr to httr2
• enrich sso message (#844). Thanks to @hadley for raising issue.
• attempt to automatically set/refresh sso credentials by calling aws cli (#844)
• moved api log level to debug and trace. This is to prevent info level being saturated by api calls.
• new PawsStreamHandler, allows paws to handle aws stream event (#842). Thankyou to @hadley for developing the initial solution in httr2.

Bug Fix:

• ensure url is set to lower case before signature

Potentially Breaking:

• deprecated custom handler for s3_unmarshal_select_object_content in favour of new PawsStreamHandler

Performance:

• migrate parse_url, parse_query_string and build_url to cpp for performance improvement.

Backend Vendor:

• migrate vendor from aws-sdk-js to aws-sdk-python boto3 (endpoint regex updated accordingly).
