Move TLS/cert handling to main app
- apply changes in proxy plugin and TLS interceptor - add HTTPS proxy support - move ca-generation command to main app - minor refactoring to improve API stability - move mocks to extra packages to avoid cycling imports - fix bug in multi-port configuration - change HTTP proxy to redirect to HTTP mock instead of maintaining custom rules
