If we want `Selector` to be general purpose, we need to clean it up a bit.
When implementing a selector, you need to have 3 things: the list of
selections, the evaluation criteria and the selection key. For this case, we
could simplify it to just the list of selections and the selection key. The
evaluation criteria can be defaulted to a simple "AND all of the keys except
the select key". An example of how it should look
```
"behaviorStrategy": {
"type": "default",
"selectKey": "category",
"categorySelectors": [
{
"category": "low-throughput",
"context.tags": {
"billingCategory": [
"streaming_ingestion"
]
},
"task": {
"datasource": [
"wikipedia"
]
}
},
{
"category": "medium-throughput",
"task": {
"type": [
"index_kafka"
]
}
}
]
}
```
So now the evaluator would look at all of the keys EXCEPT `category` and one
a match, it will return the category.
What do you think?
