The module is supposed to contain minimal set of files that establish
public etcd server API. In particular client libraries for etcd built in
different languages might want to depend on this file.
1. setting environment variable cannot be in quote
2. "--race" testing for unit tests is supposed to be part of linux-amd64-unit-4-cpu-race config.
3. 'run' function in test script should log_error in case of failed
command (wrong operator for ints comparison in bash).
This refactoring offers following benefits:
- Unified way how go test commands are being called (in terms of flags intepretation)
- Uses standard go mechanisms (like go lists) to find files/packages that are subject for test. The mechanism are module aware.
- Added instruction how to install tools needed for the tests/checkers.
- Added colors to the output to make it easier to spot any failure.
