Tester

[thiagoftsm]

Summary

This PR modifies the previous tester location. Also, it brings a new tester compatible with the new structure we are building in the netdata/netdata repo

Test Plan

1. Get binaries according to your C library from [this](ADD ACTIONS LINK HERE) link and extract them inside a directory, for example: ../artifacts.
   You can also get everything for glibc [here](UPLOAD FILE WITH ALL BINARIES TO SIMPLIFY REVIEWERS).

2. Extract them running:

   $ for i in `ls *.zip`; do unzip $i; rm .gitkeep ; rm $i; done
   $ for i in `ls *.xz`; do tar -xf $i; rm $i* ; done

3. Compile branch an run the following tests:

   # make clean; make tester
   # for i in `seq 0 3`; do ./tester/legacy_test --netdata-path ../artifacts --content --iteration 1 --pid $i --log-path file_pid$i.txt; done

4. Every test should ends with Success, unless you do not have a specific target (function) available.
