Influx config issues

[johnf]

Fixes two bugs around the config generation

First some new config variable weren't defined everywhere so that we were seeing

variable = .

instead of

variable = default_value

the second issue was related to the new service options code refactor. Integers weren't matching the regex and were being output with quotes.

tnx ... will review the PR and soon release the new version.
