Add support for parameter max-values-per-tag

[dhoppe]

According to the changelog they added the parameter max-values-per-tag with a default of 100000. This patch should allow the user to disable this limitation, by setting max-values-per-tag to 0.

Hey @dhoppe - I've also addressed this in my refactor of this module found here: https://github.com/codylane/golja-influxdb/tree/devel.

Let me know if you have questions or concerns.
