Add possibility specifying affinity of AWX Pods. (#1139)
* Add an option to specify affinity rules for the awx pod In some cases, you may want to use affinity rules instead of a node selector so you can have more flexbility. For example if you want to have "soft" rules i.e. run my pod on this node if possible otherwise run it anywhere * Rename `node_affinity` to `affinity` * Maintain defaults and CSV * Add fields validation Co-authored-by: Olivier <oliverf1ca@yahoo.com>

the AWX pods to run only on the nodes that match all the specified key/value pairs. `tolerations` and `postgres_tolerations` allow the AWX

pods to be scheduled onto nodes with matching taints.
|

The ability to specify topologySpreadConstraints is also allowed through `topology_spread_constraints`
|

If you want to use affinity rules for your AWX pod you can use the `affinity` option.
