treewide: change maintainer from Daniel Danzberger to me

Change PKG_MAINTAINER from Daniel Danzberger <redacted>
to Alexandru Ardelean <redacted> for:
- python-boto3
- python-botocore
- python-awscli
- python-colorama
- python-docutils
- python-jmespath
- python-psycopg2
- python-rsa
- python-s3transfer

These packages seem pretty neglected and the community has been
updating them periodically. Will pick these up to keep them
maintained.
