Auto-encrypt licensing and database passwords first time Thingworx runs

[Timo697]

With Thingworx Platform v8.4's new way of encrypting passwords, I think it would be nice to take it one step further.  Since Thingworx creates the KeyStore file the first time it runs.  I think it would be great if Thingworx would then automatically set the encrypt.licensing.password and encrypt.db.password from the platform-settings.json file.  Then, the user doesn't have to use the Security Management Tool unless the passwords need to be changed.  And if the user wanted, all that would need to be done is to change the unencrypted passwords for licensing and database to "encrypt.licensing.password" and "encrypt.db.password" respectively.

Please note that the point of putting the passwords into the keystore is to avoid exposing them in platform settings in plain text which was done for security reasons. While it is possible to pass in most of the passwords in platform settings as plaintext instead of using the keystore, but it is strongly not recommended.
