This pull request includes a small "security hardening" change.

It allows operator to configure value for SameSite attribute (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite, https://web.dev/samesite-cookies-explained/) which is set with the auth-token cookie we set in some situations (e.g. when authenticating via st2web and similar).

The value defaults to Lax which should work as a good secure default (defining it to Strict may break some in some situations, see the link above).

TODO

@Kami
Add support for setting custom value for SameSite attribute for
44d4381 
"auth-token" cookie we set when authentication against st2api from
st2web.

For backward compatibility reasons it defaults to none.

I noticed we also don't set secure flag for the cookie.

I will also add an option for that and default it to True since it's a best security practice.

In case someone doesn't run StackStorm over https (bad idea), they will need to set it to False. I will open st2docs upgrade notes entry which documents how to do that.

Also keep in mind that this cookie is pretty much only used when logging via token / api key in query parameters (which pretty much only means st2web for our official stuff).

Use better options name, also allow user to set "secure" value for auth
70d32b5

Also default SameSite attribute to Lax.

Ooh. nice.
I have a doc wording suggestion committed, and a question about none vs None.

@cognifloyd I pushed a change which renames None to unset (which I also think it's better).

Hopefully CI and tests will pass since my local dev environment is totally toast and I don't have multiple hours to spend to try to fix it at this point.

Awesome. I'm not merging right now since we're in code freeze for the 3.6 release.
