[DOCS] wrong unit for recon_default, recon_max, etc...

[darkpixel]

Description
In one section of the docs, recon_default and the related settings are in "seconds", and in another section of the docs they are in "milliseconds".

Milliseconds: https://docs.saltproject.io/en/latest/ref/configuration/minion.html#recon-default
Seconds: https://docs.saltproject.io/en/latest/topics/troubleshooting/master.html#salt-master-auth-flooding

Suggested Fix
I suspect the values are supposed to be milliseconds, but I haven't looked at the code to be sure.

Additional context

I forgot to mention that the troubleshooting docs also say they should be set on the master, but those settings aren't listed in the master documentation. They are minion settings.
