## Summary
Add a new `circuit_breaker_thresholds` option:
```yaml
circuit_breaker_thresholds:
max_connections: 1
max_pending_requests: 2
max_requests: 3
max_retries: 4
max_connection_pools: 5
```
This option can be set at the global level or at the route level. Each
threshold is optional and when not set a default will be used. For
internal clusters we will disable the circuit breaker. For normal routes
we will use the envoy defaults.

Add a corresponding global setting for the existing route-level
jwt_issuer_format option. The route-level option will take precedence
when set to a non-empty string.
Add a new option for filtering to a subset of directory groups in the
Pomerium JWT and Impersonate-Group headers. Add a JWTGroupsFilter field
to both the Options struct (for a global filter) and to the Policy
struct (for per-route filter). These will be populated only from the
config protos, and not from a config file.
If either filter is set, then for each of a user's groups, the group
name or group ID will be added to the JWT groups claim only if it is an
exact string match with one of the elements of either filter.
