[LEDE-DEV] [RFC] Package for getting ACME (Letsencrypt) certs

[Toke Høiland-Jørgensen]

Hi

I just pushed the 'acme' package to the packages repository, which is a
wrapper around the acme.sh client for letsencrypt (see
https://github.com/Neilpang/acme.sh). It adds uci config and interaction
with uhttpd, so that getting letsencrypt certificates on a router should
be a simple matter of editing a uci config file (assuming DNS is already
setup correctly).

Testing and feedback very much appreciated. I suppose it'll show up in
nightly builds soonish. :)
