feat(analytics): refactor and introduce analytics APIs to accomodate OrgLevel, MerchantLevel and ProfileLevel authentication

[tsdk02]

Currently, we are using only MerchantID for obtaining the analytics through metrics and filters.

We are now introducing OrgLevel, MerchantLevel and ProfileLevel authentication for analytics, so we need to do the following:

• refactor the existing MerchantLevel APIs
• introduce new OrgLevel APIs
• introduce new ProfileLevel APIs

The levels are described as:

    OrgLevel {
        org_id: id_type::OrganizationId,
    },
    MerchantLevel {
        org_id: id_type::OrganizationId,
        merchant_ids: Vec<id_type::MerchantId>,
    },
    ProfileLevel {
        org_id: id_type::OrganizationId,
        merchant_id: id_type::MerchantId,
        profile_ids: Vec<id_type::ProfileId>,
    }
