Remove timeouts and logging setters from Auth0 class

[lbalmaceda]

Changes

This class is shared across the 3 clients (both APIs & WebAuth). It is a good place to share setup options, common across the entire library. Previously it supported being set read/connect timeouts and enabling the HTTP logger. Since that logic is too coupled with the DefaultClient implementation, this PR removes these properties from the Auth0 class in favor of keeping them in the client implementation instead.

The summary of removed methods:

• setter/getter for isLoggingEnabled
• setter/getter for connectTimeoutInSeconds
• setter/getter for readTimeoutInSeconds
