[BUG] [Flytescheduler] Fixed rate scheduler doesn't respect the initial startTime after a restart

[pmahindrakar-oss]

Describe the bug

Fixed rate scheduler allows to schedule flyte executions at defined regular intervals.
Rates supported are hour, day and minutes.

When scheduler starts and its given a fixed rate schedule then it uses the current time to schedule new executions at an interval provided by fixed rate

In case the scheduler restarts , it should use the last known time stamp of the execution if available from the snapshot or use the updatedAt time to start the new fixed rate schedule.

Expected behavior

Fixed rate scheduler should schedule new executions using the last know executions time or using the updatedAt timestamp of the schedule
