Anthony Lin 4c71cc2c83 Refactor Armada Operator
We will move away from the usage of if/else block and will instead
make use of inheritance (armada base operator) and task specific
operators in our dags to execute the workflow.

We also added timeout option for client read so that the CI/CD team
can set other values for the execution of armada tasks (the default
time out is currently set to 1hr for all tasks).

"""update_site
The top-level orchestration DAG for updating a site using the Undercloud
platform.
TODO: We will disable pre-flight checks for now and will revisit it at
a later date. The pre-flight checks will be more targeted in the
case of 'update_site' and will include specific checks on things
like coredns, calico and ceph.
