Reuse connections

[hoolioh]

What does this PR do?

This PR modifies send_data module and send_with_retry function so they can accept an HttpClient. This leads to some benefits:

• Since the http client (based on hyper) maintain a pool of connections they can be reused allowing to avoid unnecessary TCP handshakes with the agent.
• Avoid constantly recreating the client in the send functions.
• Allow to the caller to handle the connection pool and the proxy configuration.
