AdvancedSearch: Add a feature to hide products based on parameters

[Draykee]

Usecase:

• Specific: In order to publish an app to the iOS AppStore the app is required to allow blocking users. In this case, we can't display the products of another user anymore.
• General: We need a feature, that hides products from a user. Maybe because he doesn't want to see it anymore, because it's blocked content, or maybe because of other parameters that are disallowing access.

Implementation with elasticsearch
In the past, we used the elasticsearch plugin like this:

// Overwrote the search query:
if (ctx.activeUserId) {
    const owner = await this.productOwnerService.getOwner(ctx);
    // Apply list of blocked users for search input
    searchInput.blocked = owner.customFields.blockedUsers ?? [];
    searchInput.blockedBy = owner.customFields.blockedBy ?? [];
}

const result = await this.elasticsearchService.search(ctx, searchInput, true);

// Inside the elasticsearch config:
mapQuery: (query: any, input: ExtendedSearchInput, searchConfig: DeepRequired<SearchConfig>) => {
    // Don't display product of a block user
    const { blocked = [], blockedBy = [] } = input;
    if (blocked.length > 0 || blockedBy.length > 0) {
        query.bool = {
            ...query.bool,
            must_not: {
                terms: {
                    'product-ownerId.keyword': [...blocked, ...blockedBy],
                },
            },
        };
    }
}
