feat: PC-11814 budget adjustment support for sloctl (#56)

## Motivation

Add support for new`BudgetAdjustment` kind.

## Release Notes

New BudgetAdjustment kind which allows customers to schedule recurring
future events that should be excluded from the Error Budget calculations
in their SLOs. This PR introduces new commands such as `sloctl get
budgetadjustment`, `sloctl delete budgetadjustment`
