Allow user modification of access and error log in vhost.

[vrillusions]

Motivation for this is some vhosts I didn't want to log anything. The way I did it feels clunky to me but I try to favor cleaner templates over manifests. Was going to add similar to logic to server logs for completeness. First wanted to check that this is alright vs doing something where logic is part template and part manifest (ie keep the assembled default log in template and use if blocks around it.

Also worth mentioning there's no need to do this to to location resource as the additional config thing can add them to turn off logging per location

Hello, @vrillusions
It's really good changes. Thanks.
Please add new variable to vhost template with ssl: vhost_ssl_header.erb

[vrillusions]

OK made change to ssl template as well as making sure it adds the same "ssl-" prefix to logname.

Actually hold off on pulling, both access_log and error_log can take optional parameters after it so the validate path check shouldn't be in there.

(edit)OK that should be the last commit.

OK just to get this all good and done with I did the same for logs at server level. Although right now to make it clear where the logs are located in the config they're not consistent variable names. the error log is called "nginx_error_log" and then the access log is called "http_access_log" as that's the section its in.

Thanks for you code. I'm testing, fix simple bug and add new PR #120

[vrillusions]

fwiw just did a fresh merge of master and fixed a couple minor conflicts but otherwise is working as expected.

[vrillusions]

I verified my fix is in latest master now that #120 is merged.
