Call options are not documented and non-obvious

On https://googleapis.dev/nodejs/tasks/latest/v2.CloudTasksClient.html#createTask, what are `options`?

Following the link to https://googleapis.github.io/gax-nodejs/interfaces/CallOptions.html is of no help either.

I'd like to know what they mean and what are the defaults.

It seems `timeout` is in milliseconds. I've seen this fail a few times so I am somewhat confident that this is what it is.

However, couple more things:

1. it seems to be a "connect" timeout not the timeout for the creating task operation. I've seen the operation succeed in tail-cases after 10 seconds when my time out is 100 milliseconds.

2. Not sure what `maxRetries` is -- changing it has any effect if `timeout` fails. I'd have thought it would retry the configured number of times.
