## Problem
In many places in test code, paths are built manually from what
NeonEnv.tenant_dir and NeonEnv.timeline_dir could do.
## Summary of changes
1. NeonEnv.tenant_dir and NeonEnv.timeline_dir moved under class
NeonPageserver as the path they use is per-pageserver instance.
2. Used these everywhere to replace manual path building

We use the term "endpoint" in for compute Postgres nodes in the web UI
and user-facing documentation now. Adjust the nomenclature in the code.
This changes the name of the "neon_local pg" command to "neon_local
endpoint". Also adjust names of classes, variables etc. in the python
tests accordingly.
This also changes the directory structure so that endpoints are now
stored in:
.neon/endpoints/<endpoint id>
instead of:
.neon/pgdatadirs/tenants/<tenant_id>/<endpoint (node) name>
The tenant ID is no longer part of the path. That means that you
cannot have two endpoints with the same name/ID in two different
tenants anymore. That's consistent with how we treat endpoints in the
real control plane and proxy: the endpoint ID must be globally unique.
