add support resolver envs

[davixcky]

This fixes an issue that modify the order of the vars when applying the constraints (only noticeable when adding more constraints, for example OTHER_VAR)

SIGNADOT_SANDBOX_NAME local-hotrod-frontend-dep
SIGNADOT_SANDBOX_ROUTING_KEY 1zhhm5t7bk9pl
OTHER_VAR $(SIGNADOT_SANDBOX_NAMESPACE)_$(SIGNADOT_SANDBOX_NAME)
SIGNADOT_SANDBOX_NAMESPACE rk-$(SIGNADOT_SANDBOX_ROUTING_KEY)

When was defined as

SIGNADOT_SANDBOX_NAME local-hotrod-frontend-dep
SIGNADOT_SANDBOX_ROUTING_KEY 1zhhm5t7bk9pl
SIGNADOT_SANDBOX_NAMESPACE rk-$(SIGNADOT_SANDBOX_ROUTING_KEY)
OTHER_VAR $(SIGNADOT_SANDBOX_NAMESPACE)_$(SIGNADOT_SANDBOX_NAME)

It also add the support to resolve the env by calling the internal method in libconnect

Before

$ ./signadot sb get-env local-hotrod-frontend-dep
export SIGNADOT_BASELINE_KIND="Deployment"                                             # constant
export SIGNADOT_BASELINE_NAMESPACE="hotrod-2"                                          # fieldRef: metadata.namespace
export SIGNADOT_BASELINE_NAME="frontend"                                               # constant
export LOCATION_ADDR="location.$(SIGNADOT_BASELINE_NAMESPACE):8081"                    # constant
export REDIS_ADDR="redis.$(SIGNADOT_BASELINE_NAMESPACE):6379"                          # constant
export KAFKA_BROKER_ADDR="kafka-headless.$(SIGNADOT_BASELINE_NAMESPACE):9092"          # constant
export OTEL_EXPORTER_OTLP_ENDPOINT="http://jaeger.$(SIGNADOT_BASELINE_NAMESPACE):4318" # constant
export SIGNADOT_SANDBOX_NAME="local-hotrod-frontend-dep"                               # constant (override)
export SIGNADOT_SANDBOX_ROUTING_KEY="1zhhm5t7bk9pl"                                    # constant (override)

After

$ ./signadot sb get-env local-hotrod-frontend-dep
export SIGNADOT_BASELINE_KIND="Deployment"                       # constant
export SIGNADOT_BASELINE_NAMESPACE="hotrod-2"                    # fieldRef: metadata.namespace
export SIGNADOT_BASELINE_NAME="frontend"                         # constant
export LOCATION_ADDR="location.hotrod-2:8081"                    # constant
export REDIS_ADDR="redis.hotrod-2:6379"                          # constant
export KAFKA_BROKER_ADDR="kafka-headless.hotrod-2:9092"          # constant
export OTEL_EXPORTER_OTLP_ENDPOINT="http://jaeger.hotrod-2:4318" # constant
export SIGNADOT_SANDBOX_NAME="local-hotrod-frontend-dep"         # constant (override)
export SIGNADOT_SANDBOX_ROUTING_KEY="1zhhm5t7bk9pl"              # constant (override)

LGTM (still some work on the corresponding libconnect PR thought, and remember to update the go.mod/go.sum with go get and go mod tidy after the libconnect PR merges)

[scott-cotton]

This file looks like an accidental addition?

[davixcky]

Yes, removed.
