Overriding Cypress' before and after methods

We are using Cypress.io to build our automation suite. We have a requirement to seed our database before every test and to clear the data afterward. This could be done like below.

describe('Our test suite', function() {
  before(function () {
    //loadDbSeed is a custom command that will load the seed file based on the spec file
    seed = cy.loadDbSeed()
    cy.task('seed:db', seed)
  })

  it('should be true', function() {
    //Some test with some action followed by an assertion
    cy.visit('/some-page')
    cy.get('[data-cy="identifier"]')
      .click()
    expect(true).to.equal(true)
  })

  after(function () {
    // clearDb is a custom command that will clear out the DB.
    // We are still debating if we must clear the DB after the tests.
    // But we might still need to do some common actions for the entire suite after
    cy.clearDb()
  })
})

The problem we see is that the same before and after operations will be required for all our test suites. So we would like to override these methods so that our tests are something like this.

describe('Our test suite', function() {
  before(function () {
    // DB seeding is done automatically
    // Write only custom before steps required for this test
  })

  it('should be true', function() {
    //Some test with some action followed by an assertion
    cy.visit('/some-page')
    cy.get('[data-cy="identifier"]')
      .click()
    expect(true).to.equal(true)
  })

  after(function () {
    // DB clearing is done automatically
    // Write only custom after steps required for this test
  })
})

How do we achieve this? I have been digging around in the Cypress code and haven't found anything obvious.
