Integrate Lake Formation into the project

[fabdy]

We want integrate AWS Lake Formation into our current stack via CDK. As L2-constructs do not exist, we will have to write our own.

Create the following stack:

IAM User: lf-datalake-admin
appropriate IAM roles and assign them to the user
assign the IAM user as the data lake admin
give IAM user permissions (in LF) to create databases/tables
register our three buckets to be managed by Lake Formation as the data lake
two analyst users
one with visibility to PII data
one without access/visibility to PII data
