Deploy an EDS and update it to have a canary deployment:

• pause the canary with kubectl eds canary pause <eds-name> command
• check the status of the ERS and EDS. they should have a canary-pause condition with status true.
• validate directly the EDS with kubectl eds canary validate <eds-name>.

validation:

• check the status of the ERS, the canary-pause condition status should be false now.
• check the status of the EDS, the canary-pause condition status should be false now.
