Add profiler.uri.stat.collect.http.method option to collect uri statistics with http methods

[ga-ram]

Current URI statistics only collects URI.
When an application uses RESTful APIs, a single URI can have multiple behaviours (e.g., GET /user and DELETE /user) so it is worth collecting URI with http methods.

When profiler.uri.stat.collect.http.method = false (default value), Pinpoint agent will behave the same as before.
When profiler.uri.stat.collect.http.method = true, Pinpoint agent will collect URI statistics with a key httpMethod URI(GET /user, DELETE /user) instead of just URI (/user).
