[trentm]

We support pino@6, pino@7, pino@8, and winston@3.

This adds "TAV" (test-all-versions) tests to test against supported versions of pino and winston. I didn't bother with morgan because there hasn't been a new release of it for years. CI is setup to run this once per week.

Here are npm run tav runs for pino and winston using node v16:

% npm run tav

> @elastic/[email protected] tav
> tav --quiet

-- required packages ["[email protected]"]
-- installing ["[email protected]"]
-- running test "npm test" with pino (env: {})
-- required packages ["[email protected]"]
-- installing ["[email protected]"]
-- running test "npm test" with pino (env: {})
-- required packages ["[email protected]"]
-- installing ["[email protected]"]
-- running test "npm test" with pino (env: {})
-- required packages ["[email protected]"]
-- installing ["[email protected]"]
-- running test "npm test" with pino (env: {})
-- required packages ["[email protected]"]
-- installing ["[email protected]"]
-- running test "npm test" with pino (env: {})
-- required packages ["[email protected]"]
-- installing ["[email protected]"]
-- running test "npm test" with pino (env: {})
-- ok

I did manually do a run with all pino versions, but that's too
many versions.
