[Eventing][enforce-tls]: handler stuck in deploying state

Build - 7.0.2 - 6504

STEPS TO REPRODUCE

• Disable auto failover and enable n2n encryption.
• Create and deploy eventing handler.
• Load docs into source bucket, mutations are processed.
• Pause eventing handler.
• Resume eventing handler.
• While handler is in deploying state, enforce tls by changing ClusterEncryptionLevel to strict.

Handler is forever stuck in deploying state.

On 10.112.190.102
