Role gencfg_jdbc generates file jdbc.yml. mas install does not work with that

[ghost]

In mas install it is requiring a specific file name and extension. Even if you set the name right as expected, the extension .yml is also not recognized, so you have to change to .yaml instead.

So, the fix suggested here is to make the role result match with what mas install requires.

A plus would be to make mas install to accept both .yml and .yaml extensions.
