#1423 : Autoinstrumentation for proxymode

[fred-maussion]

This pull request change the manual APM instrumentation to autoinstrumented to enable distributed tracing for outbound calls made in proxy mode.

Changes:

• The http.Client in proxymode.go is now instrumented using apmhttp.WrapRoundTripper to automatically trace outbound requests.
• The request context is propagated to the outbound calls
• Remove manual apm.StartSpan calls in favor of the new automatic instrumentation.
