[gateway] implicit consent for audit logs

[tcompiegne]

🌈 Feature

As a 'security domain owner'

I want to 'retrieve more information about my user audit logs (user_agent, ip_address)'

So that 'I can implement new workflow (automatic webauthn registration for example)'

🌄 Additional information

• Currently the user need to explicitly consent to store these values via https://docs.gravitee.io/am/current/am_breaking_changes_3.18.html#ip_user_agent_and_user_consent, but it's possible that the user has already consent prior to this step by any means.
• A customer might also want to by pass this step
• A new option will be added in the gravitee.yml to enable this behavior

✅ Acceptance criteria

• Given 'an end user When 'I register a new webauthn credential' Then 'I should have access to the user_agent and ip_address in my audit logs if the option is enabled'
• Given 'an end user When 'I sign-in' Then 'I should have access to the user_agent and ip_address in my audit logs if the option is enabled'

☑️ Developer sub-tasks

• Jest test for acceptance criteria
