feat: sless_job terraform resource + jobs REST API

Operator (v0.1.4):
- internal/api/handler/jobs.go: CreateJob/GetJob/DeleteJob handlers
- internal/api/router.go: POST/GET/DELETE /v1/namespaces/{ns}/jobs/{name}

Terraform provider (v0.1.2):
- client.go: JobRequest/JobResponse + CreateJob/GetJob/DeleteJob/WaitJobDone
- resources/job_resource.go: sless_job resource (Create blocks until Succeeded/Failed)
- provider.go: register NewJobResource

Deploy:
- operator:v0.1.4 deployed and running in cluster
- provider v0.1.2 published to terra.k8c.ru
