Repackage goenvtemplator to use more recent sprig library

Currently goenvtemplator uses quite old sprig library, it would be great to move to more recent version to support advanced functions like regexReplaceAll.

$ goenvtemplator2 -version
2017/08/15 14:28:46 Version: -2.0.0-rc2
$ goenvtemplator2 -template $PWD/index.html.tmpl:$PWD/index.htmL
2017/08/15 14:28:14 Error while generating '/home/freznicek/prjs/szn/sources/Sklik-DevOps/helm-registry.git/docs/index.html.tmpl' -> '/home/freznicek/prjs/szn/sources/Sklik-DevOps/helm-registry.git/docs/index.htmL'. template: index.html.tmpl:8: function "regexReplaceAll" not defined

It looks that goenvtemplator2 uses this particular revision https://github.com/Masterminds/sprig/tree/69011c0cd9b4d2e0733c4d9e2c8e2a5a0d0a2f2f which is from Dec 2016.

Current workaround is to use replace instead of more powerfull regexReplaceAll.

This has no priority for us right now. Not working on this for at least next 2 weeks. Will be back soon.

This becomes more and more important since Sprig changed their functions radically and upgrade would already introduce breaking change.

The problem is that Sprig documentation has only the latest version so there is no documentation for the Sprig version we support now already.

Should we support this in v2?

[FUSAKLA]

I say let's upgrade it now in v2 when we have the chance to introduce breaking changes.
Otherwise we would wait next 2 years for another major release :)
