[collectd] write_http plugin - dynamic tag

[Shirly Radco]

Thank you Marc!

It is very good to know that.

I was trying to get the tag dynamic because I'm also using Fluentd and
there I want to treat each metric differently.

The tag after the url in the write_http is used in Fluenyd to match the
record and in order to make transformations on.

I managed to manipulate the tag to what I needed finally. But it will be
much better if it could be done in collectd.conf in the first place.

Thanks again
Shirly
