rpc: implement internal debug_ API namespace functions (#313)
* API Hello World * Added all the debug functions + more data to try implementing the GC functions * Getting transactions information * Added cpu profile first approach functions * new struct for cpuprofile and read filename from params * cpuprofile, gcstats and memstats * added comment * All endpoints returns error instead of string * Code cleanup * Changed errors messages to match go-eth returns * Removed activated flag and just using the file to check if it's running * Added new endpoints to the json_rpc.md file * GoTrace debug endpoints added * Block profile endpoint added * missing goeth calls * added debug logs * divide debug and internal api * Using ExpandHome on server configuration * Added rpc changes to changelog * Logging go trace status * Removed logger functions and moved logger errors to debug * Added more logs to go trace * Added more datailed changelog * Removed trace debug api interface * added comments * cleanup * Updated changelog * disable lint on cpuprofile rename Co-authored-by: Federico Kunze Küllmer <31522760+fedekunze@users.noreply.github.com> * return error in StopCpuProfile Co-authored-by: Federico Kunze Küllmer <31522760+fedekunze@users.noreply.github.com> * return error in StopGoTrace Co-authored-by: Federico Kunze Küllmer <31522760+fedekunze@users.noreply.github.com> * implement suggested changes Co-authored-by: ramacarlucho <ramirocarlucho@gmail.com> Co-authored-by: Federico Kunze Küllmer <31522760+fedekunze@users.noreply.github.com>
