Reduce log output

[smhex]

Is your feature request related to a problem? Please describe.
For every data update of my weather station the following log output is shown:

[Netatmo] Loading new data from API for: weatherstation
[Netatmo] Loading new data from API for: airquality

As I have many other plugins running the log gets filled with those messages and it is more difficult to find relevant log entries in case of errors.

Describe the solution you'd like
Introduce a config switch to disable the log output for log level info or completely suppress them.

Thank you for the PR @smhex, I really appreciate it 👌 In my limited time I focus on refactoring the plugin to use a new auth-mechanism (see #62 ). But when this is done, I will take a look at your PR

[smhex]

Don't worry! I can always create a patch for my own installation. If you need help with testing the new login method just tell.

Since the authentication-topic (#62) is hopefully done now, I will soon take a look your PR, @smhex

[skrollme]

I just merged your PR and released it as 1.0.1. Thanks for your contribution @smhex 👌
