WaitUntil doesn't wait long enough in Astra cluster creation

[weideng1]

When creating a E-tier cluster in Astra, we often encounter the following error:

$ astra -e dev db create -l AWS -k testks -n clitest -r us-east-1 -t E60
..........................................................................................unable to create '{1 AWS testks clitest <nil> us-east-1 E60 <nil>}' with error waiting for status check on create db failed because 'unable to find db id aae7d687-1083-4c04-915c-fdf79a2cef84 with status [ACTIVE] after 2700 seconds'

This can be easily fixed by allowing it to wait for 1 hour instead of 2700 seconds.
