Feature request: include "name" claim in Identity struct

[kenjenkins]

Is your feature request related to a problem? Please describe.

It looks like the Pomerium JWT will include a "name" claim by default, as of pomerium/pomerium#3238. However the sdk.Identity struct does not yet have a Name field, so there's no easy way to access this claim using the SDK.

Describe the solution you'd like

Let's add a field for this claim to the sdk.Identity struct.

Describe alternatives you've considered

Explain any additional use-cases

Additional context

It looks like someone has forked this repository in order to add a Name field: mworzala@003caf5#diff-09f9b3a1799ba8820fa8a377f22a680365e56db8ea8dab214280822f6327c01f

Added in

• Add name claim to JWT payload pomerium#3216

Looks like we also need to update docs entries as well beyond just the grafana guide e.g.

• https://www.pomerium.com/docs/capabilities/getting-users-identity
• The go SDK godocs
• Javascript sdk
• (others?)
