Rule: Enforce placement of input/output decorators

[benjamincharity]

We should enforce consistent placement for the @Input & @Output decorators.

---

Example:

// When configuration dictates 'above'
// bad:
@Input public foo: string;

// good:
@Input
public foo: string;

///////////////////////////////

// When configuration dictates 'inline'
// bad:
@Input
public foo: string;

// good:
@Input public foo: string;

---

• Create rule
  • Should allow configuration to set the decorator above the line or at the front of the line.
• Make the rule fixable
• Add rule to our ruleset for spec files
