changes that allow to build and run in both onPremise (Cockpit) and Saas environments.

Configured webpack with necessary loaders and plugins.
`AppCockpit` file and `cockpit:build` script were added for Cockpit compatibility.

We need to integrate a new API service for managing blueprints and update the Redux store to handle blueprint-related data in a Cockpit environment.
This will allow us to fetch, store, and manage blueprints effectively within the application.
Created a new 'cockpitApi' service to handle the API calls related to blueprints in cockpit env.
Added a 'blueprintsReducer' to the Redux store to manage blueprint state.
Added a new 'emptyCockpitApi' file for the blueprint API setup, including type definitions and query configurations.

- define isOnPremise boolean variable to check if its onPrem env.
- define useGetFeatureFlag hook to return false in on-premise environments and dynamically call the appropriate hook
(useFlag or useFlagWithEphemDefault) based on the feature flag name.
Improved structure by avoiding hook calls inside conditionals to adhere to React rules

we have issue when running the cockpit:build script- the symbolic
link was not created for everyone.
fix it by adding a condition that check where the cockpit definition exist in the machine and
create the symbolic link there.

add alias to webpack config
1) api alias defines the path to onPrem cockpitAp file
2) pathRes alias define path for onPrem env
3) getFeatureFlag alias define the path to file with flags
