Crud APIs for dashboards (#286)

* added signoz.db to gitignore

* model and crud methods for dashboard package

* added signoz.db to dockerignore

* feat: dashboards crud WIP

* chore: moving response format to correct file

* chore: adding dependencies for sqlite3

* feat: CRUD APIs ready for dashboards

* fix: sqlite needs cgo enabled and hence need to add some flags in building go code

* feat: provision dashboards using json

* chore: mounting dashboard folder to container
