Define user password expiry in terms of seconds

[jamesreprise]

What is the goal of this PR?

We've redefined the way we expose how long until a password expires in seconds, rather than days as was done previously.

What are the changes implemented in this PR?

• We've changed password_expiry_days to password_expiry_seconds.
• We implement the newly updated BDD steps to do with opening and closing connections, and prepare other steps for booting and configuring TypeDB for use once the TypeDB runner is available in Python

Trivial Change

• This change is trivial and does not require a code or architecture review.

Code

• Packages, classes, and methods have a single domain of responsibility.
• Packages, classes, and methods are grouped into cohesive and consistent domain model.
• The code is canonical and the minimum required to achieve the goal.
• Modules, libraries, and APIs are easy to use, robust (foolproof and not errorprone), and tested.
• Logic and naming has clear narrative that communicates the accurate intent and responsibility of each module (e.g. method, class, etc.).
• The code is algorithmically efficient and scalable for the whole application.

Architecture

• Any required refactoring is completed, and the architecture does not introduce technical debt incidentally.
• Any required build and release automations are updated and/or implemented.
• Any new components follows a consistent style with respect to the pre-existing codebase.
• The architecture intuitively reflects the application domain, and is easy to understand.
• The architecture has a well-defined hierarchy of encapsulated components.
• The architecture is extensible and scalable.

Still waiting on 2.17.0 release from both servers. Also need to update behaviour, though this is likely to be time intensive.
