Implement an endpoint to save technologies

[enriquezrene]

We need to have endpoints that can help us to manage technologies information, here are the required operations:

POST
/technologies

BODY
{
creation_date (timestamp): YYYY-MM-DD hh:mm:ss,
time_entry_id: UUID
name: technology name
}

GET
/technologies

It returns all the stored technologies

We need to create a container to persist this data. Also, we renamed the field time_entry_id to first_use_time_entry_id.

We'll use name as the only one unique field.
