Add prefixes for every headers and trailers

[chashikajw]

Purpose

This will fix the custom property override issue when the header name is defined in both the request and response arrays.

From this fix it will add REQUEST_HEADER_, RESPONSE_HEADER_ and RESPONSE_TRAILER_ prefixes for particular headers.

[analytics.adapter.customProperties]
    enabled = true
    requestHeaders = ["host","content-type","content-length", "authorization","x-forwarded-for","x-original-forwarded-for","x-client-dn", ":path", ":authority"]
    responseHeaders = ["etag", "content-type"]

customer property array will be like below.

 [REQUEST_HEADER_content-type=text/json, REQUEST_HEADER_:path=/v2/pet/findByStatus?status=available, REQUEST_HEADER_host=petstore.swagger.io, REQUEST_HEADER_:authority=petstore.swagger.io, RESPONSE_HEADER_content-type=application/json, host=petstore.swagger.io, content-type=application/json, :path=/v2/pet/findByStatus?status=available, :authority=petstore.swagger.io]

This will not remove the previous headers to keep the backword compatibility.
