Subject: [PATCH] roachtest: add delay after adding constraints

Fixes: #105506.
Fixes: #105505.

Add a delay after adding the constraints before recommissioning the
node. This allows the constraints to propagate to all nodes and avoids
replicas being added back to the node.

Epic: none

Release note: None
