Try optimizing e2e tests by removing potentially redundant sleeps from When/Then

[andrii-korotkov-verkada]

Summary

One example is When, which has a sleep for 1 second, e.g.

argo-cd/test/e2e/fixture/applicationsets/context.go

Lines 29 to 33 in 02d6866

	func (c *Context) When() *Actions {
	// in case any settings have changed, pause for 1s, not great, but fine
	time.Sleep(1 * time.Second)
	return &Actions{context: c}
	}

Maybe it can be removed or reduced. This would require some exploration and experimentation.

Motivation

Improve e2e tests run time.

Proposal

Explore why certain sleeps are there and experiment with removing them.
