prernakakkar-google ed5ef4caea feat: Create wait for tool (#885)
`
tools:
  wait_for_tool:
    kind: wait-for
description: "Tool puts chat to sleep for given timeout example 3m,10s,
5m etc. For tasks such as cluster creation no need to wait. It takes
longer time such as 8m for instance creation. Use timeout value as
default if nothing is provided"
    timeout: 10s
`

Output: 
`
