Commit Message

Add retries to getServer() (#316)

Some backstory
==============

I was attempting to use postgres_exporter with the official Docker
container (https://hub.docker.com/_/postgres) In a Kubernetes
StatefulSet, with a side-car configuration, but found that I wasn't able
to connect even with sharing the Postgres Unix listening socket, between
both containers. After copying the container over to an Alpine base I
quickly found out that the postgres_exporter was actually starting
before the main Postres container had dropped the unix socket onto the
file system, a quick work around is to write a bash for loop checking
for the existence of a unix socket, however this would require
maintaining a container, besides other users may find retries useful on
startup.

Implementation
==============

All changes are made to the getServer function and variables are
local, I was unsure if it was worth adding command line switches but
this would allow for a more sophisticated backOff loop in the future.

Hope this help, and let me know if you would like me to changes
anything.
