Increase timeout for kolla_toolbox module.

This patch increases the default timeout for
the kolla_toolbox ansible module when talking
with the docker API from the default 60 to 180 secs.

This is required on slower deployments,
specially when bootstraping an environment and fernet
tokes are in usage. For faster deployments this will
be harmless, but for slower deployments this would be
beneficial.
