tsh login timeout too aggressive, not configurable

[aberoham]

What happened:

tsh login timeout for SAML/OIDC is too quick for some scenarios, such as when the identity provider has non-immediate additional auth factors (such as email-based tokens).

If browser window does not open automatically, open it by clicking on the link:
 http://127.0.0.1:54679/[redacted]
error: timed out waiting for callback

What you expected to happen: For SAML/OIDC timeout to be configurable or simply longer than the current 60 second value

How to reproduce it (as minimally and precisely as possible): Run tsh login against an auth provider you're not currently logged into and wait 60+ seconds.

Environment:

• Teleport version (use teleport version): 3.x
• Tsh version (use tsh version): 3.x
• OS (e.g. from /etc/os-release): n/a

@klizhentas need your opinion on this, especially about simply increasing the default value to, say, 180 seconds.

sounds good
