We are using tags to be able to group features and senarios. For example, we have something like:

```
@jira=123 
Scenario: test scenario 1
...

@jira=456
Scenario: test scenario 2, known failure
...

Scenario: test scenario 3, new feature

```

Now, we are hoping to run test that are not tagged with @jira=123 or @jira=456. Because we have many features and scenarios tagged with the @jira=somevalue, it is impractical to add them all. So I am looking for a way to be able to exclude anything tagged with @jira. I tried ~@jira and "~@jira=" but no luck.
Looking at the following junit case:

[TagTest.java#testToString()](https://github.com/intuit/karate/blob/789e8c703b2359a6fd40f284c5ca81e475fa5054/karate-core/src/test/java/com/intuit/karate/core/runner/TagTest.java#L34)

Which is using "@foo=" as a tag, but was not able to find an example. Is there a way to exclude a group of scenarios tagged by @jira, regardless of the tag value ?
