- projects/apps -> /projects/{projectId}/apps

* refactor: 미사용 메서드 삭제

* refactor: copy and 개선 App, Project 테스트코드

* refactor: delete App, Project code in logbat project

- logbat_meta 프로젝트로 이전

* refactor: JPA 관련 코드 제거

* refactor: AsyncLogProcessor 생성자 개선

- this 참조 추가
- database poolsize debug로그 추가

* fix: 데이터베이스 poolsize 직접 지정

* feat: AppJDBCRepository 추가

- JDBC Template를 사용한 데이터베이스 조회 구현

* refactor: JPA 설정 제거

* fix: 에러를 반환하지 않고 빈값을 반환하도록 수정

* test: 도메인 분리로 불가능한 테스트 수정

* config: Nginx 설정 변경

* fix: 서버 주소 변경

* config: 변경된 도메인 적용

* refactor: 변수명 변경
