Interval is not taken into account

[conrad784]

I am currently running collectd plugins on the basis of your base.py

I am writing to the log what the interval is in the subclass and also when the config callback is executed.
The read_callback will be initialized with the default interval, as the config is not yet read.

May 28 21:06:14 host collectd[23258]: plugin_load: plugin "python" successfully loaded.
May 28 21:06:14 host collectd[23258]: subclass_interval: 10.0
May 28 21:06:14 host collectd[23258]: reading config
May 28 21:06:14 host collectd[23258]: base_interval: 60.0

running collectd 5.7.1-1.1 on Debian 9

Seems like #11 is not solved, what could be a solution to this initialize the read callback after reading the config?
