add rest endpoint for translate services

[mwangidennis1]

i have added a rest package which implements some rest services and augmented parts of existing code for interoperability i have also added some dependencies to name them :

1. javelin- acts as a web framework with useful stuff out of the box
2. SQLite jdbc driver -interface to communicate with SQLite database
3. hikariCp - for connection pooling
4. argon2-jvm - for hashing password purposes what i added just conforms to the first issue in the issue page The package comes with a main class which can serve as an entry point to the program
