Added possibility to change value of FILE_LOCK constant in config (at the same level as search_index option).

Hi there, thanks for the interest and the PR.

This was missing, thanks for the addition. Could you put an example entry in the example config? Looks good for merging otherwise.

[lcharkiewicz]

Hey,
I've added the example configuration also for search_index. Wanted to make it clear enough. :)

Oh, just realised that. Since it's an influxgraph configuration setting, it should be under influxgraph section in config, if you don't mind making that change.

[lcharkiewicz]

Sure, moved it to the influxdb section (I assumed you meant that one). If should be in a new, influxgraph section I'll move it.

Thanks! The code is currently failing the flake8 check - https://travis-ci.org/InfluxGraph/influxgraph/jobs/263538155
