Expose logic for creating new team configs/schemas

[traeok]

Is your feature request related to a problem? Please describe.

From the perspective of a Zowe Explorer extender, I would have to re-implement most of the logic for creating a new team config and schema. This would likely involve duplicating code that already exists in Zowe Explorer's codebase in order to access it.

Describe the solution you'd like

It would be helpful to provide some of this logic in ZE API, if possible, to avoid code duplication and to allow this feature to be leveraged by extenders.

Describe alternatives you've considered

Copy/pasting the code from Zowe Explorer itself, but this feels redundant and is not easy to maintain.

This will be helpful for the CICS extension

It would be nice to have the ability to add a custom profile if needed in the created team config instead of always the default profile attributes.
