Make documentation for Go tools to use symlinks to README.rst

- Currently, documentation for Go tools is duplicated in the user manual
  and README files. This PR makes README files single source of truth
and creates a symlincs inside docs directory.
- Fixed link to the forum in
  config/sphinx-build/_static/_templates/theme/relbar2.html (previously
mentioned PSMDB forum instead of Percona Toolkit's)
- Updated 3.6.0 release date in docs/percona-toolkit.pod
- Updated documentation for option --version in docs/percona-toolkit.pod
