[FEATURE] Remove password policy from codebase

[flyinghermit]

Describe the feature:

Since we will be supporting external user identity providers, it makes no sense to implement and support policy in trasaIDP. TRASA IDP should be minimal and any advance use case should be deferred to identity providers.

Scope of the feature:

• [ ] TRASA codebase
• [x] dashboard
• [x] server
• [ ] mobile app
• [ ] browser extension
• [ ] device agent
• [ ] website/docs
