Implemented new endpoint to update brand status.

[laz95]

Implemented following changes:

• Added brand_status table to the database to store all available brand statuses and their metadata
• Added brand_status_history table to the database to store changes to brand status, like when status of a brand was changed and by which user. Current status of a brand can be retrieved from this table by querying last added entry for that brand id.
• Added updateBrandStatus endpoint to BrandResolver.ts
• Added updateBrandStatus function to BrandService.ts that checks if user is admin and has access to brand and updates status
• Added BrandStatusHistory.ts that contains logic to change brand status and retrieve brand status from db to check if given status exists. If status is invalid, it throws exception.
• Modified tc_col_memorable-test.json to add tests for updating brand status: one test that updates brand status to DATA_READY and other test that throws INVALID STATUS exception
