Jasypt encryption

[namtruong]

This PR enables jdbc password in configuration file to be obfuscated by using jasypt library for encryption/decryption.

• To enable the feature simply replace plain-text property with encrypted value and have it wrapped inside ENC() function. I.e. "password": "ENC(ujMeokIQ9UFHSuBYetfRjQTpZASgaua3)".

• For details on how to encrypt a string using jasypt binary, see Encrypt database password section below.

Please note at the moment this encryption is only enabled on jdbc.password
