Prevent storage manager creation during validate.

Delay the instantiation of an agent object until it is actually needed.
Instantiating an agent object creates an entry in the storage_managers table,
this is not the desired behavior when validating the storage manager's credentials.

Automate - add "finished" statemachine state.
Remove unused method VMDB::Config#schema_update
Remove @@ variables that can be accessed normally via VMDB::Config.new
Remove log.line_limit setting due to the inordinate complexity.

Managing line_limit requires a lot of code, which ultimately is never
used.  Developers lose information if the log lines are truncated, and
so in practice, and by default, it is disabled.  The line_limit setting
complicates things because the value is needed to initialize the logger,
which is initialized before access to the database is available, thus
managing changes and storing that change in the database creates a
chicken-and-egg problem.
Remove unused lib/vmdb/miq_appliance.rb

Originally introduced in https://bugzilla.redhat.com/show_bug.cgi?id=MANAGEIQ-2576

Removed unused method VMDB::Initializer.set_network.
Move VMDB::Config.VERSION, BUILD, and BUILD_NUMBER to Vmdb::Appliance

Rename VMDB::Initializer to Vmdb::Intializer for consistency
Remove unused method VMDB::Config.queue_size
Move config validation and activation into their own classes.

Cloud instance best fit via Automate State Machine
Remove unused method VMDB::Config.log_network_address.

It used to be used to gate the inclusion of app/helpers/patches/abstract_request_patch.rb,
from around 2008, but that file is no longer in our code base.
