Multiple instance

[frenkye]

Hi,
thank you for the exporter. Do you have any plans to support multiple instance on one server?
In my case we have up to 5 clusters on different port like:

1. 9.6 main 5432
2. 9.6 test 5433
3. 9.4 main 5434
4. etc ..

Would be nice, if we don't have to start N exporters depend on how much clusters we running.

Would be happy to take this up and contribute if I can get some guidance from the community.

The exporter should 90% be ready for this. The work is figuring out what globals need to be exporter-local and how to handle tagging different metrics.

@wrouesnel I got the first part but need some more clarification on the second half of your reply.
You mean how to tag (all the) metrics from multiple (postgres) servers?

[frenkye]

@wrouesnel Maybe by strip port from DATA_SOURCE_NAME? Which could also be overwritten by different ENV variable like DATA_CLUSTER_ALIAS, so there will be option for custom tagging?

This is pending me merging #157 I think since that will include a lot of the required changes.
