feat: new DocType "Employment Contract"

[barredterra]

Add a new DocType to capture the most relevant data of an employment contract. When changes to the contract occur, we can use cancel + amend to update the contract while leaving a track record.

What is the difference to "job-offer" from HRMS?

[barredterra]

A different trade-off between standardization and flexibility. This doctype tries to model a german employment contract while Job Offer is just a set of arbitrary terms.

My Brainstorming:

• Disadvantage with Cancel + Amend: Employee has no valid Employement Contract for a short time. This might lead to errors, if other functions will rely on a valid Employement Contract in the future.
• Challenge: Differentiate between instances/companies that use the Employement Contract or simple float fields in Employee to record the working time. Goal: No data redundancy.
• Vacation per Year: If this won't be used to create Leave Allocations, it will be redundant if Leaves are used in the system.
• This probably would change the configuration of a Holiday List: Now only proper bank holidays should be in there. (Additional advantage: We could finally automize updation of a Holiday List, since we now have all data we need to do that if there are no weekly offs in the holiday list)

Let's plan this for version-16, maybe contribute to hrms.
