[Common] Ability to store user preferences

[NipuniBhagya]

Is your feature request related to a problem? Please describe.
In the current developer portal, we are unable to store the user preferences and therefore they'll be lost when the user logs out of the application.

Describe the solution you'd like
The better approach to handle this would be to store these preferences in the local storage so that even if the user logs out the required data will be persisted.
