Poor man's maintanence mode though ip tables

Move sync-plans checks to pre/post migrations

Introduce run_strategy for scenarios

Health-check scenarios are better to run all steps regardless of errors
(:fail_slow strategy), while the migration scenarios should fail as soon
as first failure happens (:fail_fast strategy).

By default, the scenarios are treated as `:fail_fast`.

Full upgrade scenario

This commit intoroduces more structured upgrade scenario consisting of
this scenarios:

• pre_upgrade_check - non-modifying checks: is the system ready?
• pre_migrations - modifying procedures before source update
• migrations - source update and main migrations...

Retain original objects while Tsorting. TSort create label graph and then convert to object graph

Define order using ruby TSort

Turn hammer feature into a utils class

After looking more into this, I think the util class is actually better
fit for the hammer case. I've also removed the detection of the
credentials from hammer configuration, as we actually don't need
the credentials by our own.

Introduce hammer as a feature

Shellescaping and password filtering support in system helper

Support code for allowing filering out sensitive data from logs
+ properly escaping user-specified variables (such as password)

Fixes #5 - enhanced logger feature

2. Now, logs are stored into file under foreman-maintain/log directory in debug mode
3. Number of log files set to 10 i.e
when, there would be 11 files remaining, the oldest one will be deleted...

Make the spinner opt-in, not opt-out

The default spinner caused issues when one needs to interact with the
user (printing additional messages). As it's needed only for long
running actions, it should not be enforced by default.

Set next steps with the assert check

This allows adding more assertions to the check, each adding their own
next steps.

Run confine against classes, not objects

This allows us to have multiple objects of the same procedure in the
system, differing in the constructor parameters. Useful for parametrized
procedures.

Extract metadata DSL to separate namespace

Having the DSL methods directly on the classes caused issues when
needing to query the metadata later.

Corrected the syntax.
