[SPEC] Improvements to restaker unbond flow

[1xstj]

          Random thoughts of whether we should support...

2000 total tokens bonded to validation, 50% restaking threshold which means I can restake 1000 tokens.

• Scenario A: 500 tokens restaked. Should I be able to unbond 1000 tokens? If I'm reported for misbehavior it doesn't matter, there's still 50% of the total bond >= my active restaking amount.
• Scenario B: Let's imagine the 1000 restaked tokens have 0 active services (no jobs active). Should I be able to delete my profile AND unbond without subjecting it to 2 delays (1 for deleting profile / restake and another for unbonding the tokens after).

Salman's question/scenario: What should happen when 1000 tokens bonded, 500/1000 tokens restaked (max restake) and the validator is slashed from a consensus misbehavior?
