support multiple names for one cert and select authenticator based on variable

[rngadam]

fixes:

• missing hostname parameter (-d)
• uses a list of hosts instead of just the first host
• selects between web authenticator and standalone based on the variable being present or not

the first two are not broken, they are that way intentionally:

-d is just specified in {{ letsencrypt_command }} using a for loop, which works in a way that is more friendly for the rate limits (i believe are currently 5 certs per week per second level domain or something). By requesting multiple names for one cert instead of one cert per name, we deplete the rate limit less quickly. It gets stored in a folder named by the first domain in the list.

I like the third one, if you can take the other stuff out i'll accept

shit, I accidently hit the close button... :/

More info on the rate limiting stuff.

modified to work both nicely with the rate limit and the authenticator selection

also made the virtualenv install for Debian only (fails on Ubuntu)

[thefinn93]

If Ubuntu doesn't have the package names of Debian, than Ubuntu should get a special case. Also, it should be a separate pull request. Once again, the multiple domain thing is handled in defaults.yml, which builds them into letsencrypt_command. Please make one pull request per change so they can each be discussed individually.

Can I assume this should be closed in favor of #8?

[rngadam]

sure
