HDDS-3411. Switch Recon SQL DB to Derby.

[avijayanhwx]

What changes were proposed in this pull request?

Recon currently uses Sqlite as its defacto SQL DB with an option to configure other JDBC compatible databases. However, on some platforms like the IBM power pc, this causes problems from compile time since it does not have the sqlite native driver. This task aims to change the default SQL DB used by Recon to Derby, but retains the out of the box support (no need to supply the driver) for Sqlite as well.

What is the link to the Apache JIRA

https://issues.apache.org/jira/browse/HDDS-3411

How was this patch tested?

Added unit tests.
Manually tested on docker with Derby and Sqlite.
Built the recon modules on IBM PPC host.
