Not pinging when new device is discovered

Related to https://github.com/thomasloven/hass-plejd/issues/66.

It seems that doing a ping when a new device is discovered causes flooding of Bluetooth traffic. Not sure if this happens to everyone but for me I get quite a lot of "discovered" events, even from Bluetooth devices that are not Plejd. Every time this happens it triggers a ping, which in turn discovers more devices.

I added some logging in the _discovered function and this is a sample of what I see in my HA logs:

I don't know why the ping was added in the first place, but I've removed it and has been running flawlessly on my HA for weeks now.
