[backend] feat(multi-tenancy): xtmhub auto-register, contact-us and clean up PlatformSettings (#5575)

[carinelebas]

Proposed changes

• Use new entitiy TenantXtmHubRegistration for auto register and contact us endpoints
• send tenant id in auto-register
• clean up now useless registration information in platform settings

Testing Instructions

Auto-register:

• request an openaev trial on xtmhub, set it to provisioning state with your platform id, get the token.
• call the autoregister endpoint with curl:

curl -X PUT 'http://localhost:3001/api/xtmhub/auto-register' -d '{"token": "<token>"}'  -H "Content-Type: application/json"  -b '<JSESSIONID cookie>'

• check default tenant is successfully registered

contact-us:

• setup a trial license
• click on 'reach out to sales' in the banner: check the message is successfully sent.

Clean up:

• check in the network panel, for the settings call, that xtmhub registration information are not sent anymore
