[Fix] Allow using HTTP_ Proxy settings with trust_env

Use HTTP_PROXY environment variable

Both httpx and aiohttp libraries use urllib.request.getproxies from environment variables. Before client initialization, you may set proxy (and optional SSL_CERT_FILE) by setting the environment variables:

import litellm
litellm.aiohttp_trust_env = True

export HTTPS_PROXY='http://username:password@proxy_uri:port'

export HTTPS_PROXY='http://username:password@proxy_uri:port'
export AIOHTTP_TRUST_ENV='True'
