Code Issues Proposed changes

Merge builder.Builder and builder.Jenkins

Browse Source 
Since both of these classes essentially build on basic functionality
provided by jenkins.Jenkins, merge them into a single class. Name this
class "JenkinsManager" to avoid confusion with jenkins.Jenkins.

Also moves some tests for update timeout configuration into the
tests.cmd.test_config module from tests.cmd.subcommand.test_update
module, replacing those tests with skipped stubs as reminders to
figure out a better way later.
