Feature: support non-default browser launching for SSO/Login

[Kirill888]

I would like to use non-default system browser to complete SSO and web console logins. Currently this is only supported via --stdout option (although there is a bug #868 that makes this workflow somewhat awkward to use).

aws-cli uses BROWSER environment variable to determine how to open SSO urls(aws/aws-cli#5301 (comment)). It would be nice if aws-vault supported the same. Alternatively a command line option would work too. This would also enable #755 but in a more generic way.

this seems to work fine on MacOS:

env BROWSER=Safari aws-vault login some-profile

I would also be very interested in this feature, as we are using the non standard AD profile for AWS SSO so we need a second browser to login to AWS SSO. This feature would simplify the workflow
