TUN-9583: set proper url and hostname for cloudflared tail command

Browse Source 
This commit adds support for FedRAMP environments. Cloudflared will
now dynamically configure the management hostname and API URL, switching 
to FedRAMP-specific values like `management.fed.argotunnel.com` and `https://api.fed.cloudflare.com/client/v4`
when a FedRAMP endpoint is detected.

Key to this is an enhanced `ParseToken` function, which now includes an `IsFed()`
method to determine if a management token's issuer is `fed-tunnelstore`. This allows
cloudflared to correctly identify and operate within a FedRAMP context, ensuring 
proper connectivity.

Closes TUN-9583
