Makes it consistent with the "timeline create" and "timeline import"
commands, which allowed you to pass the timeline id as argument. This
also makes it unnecessary to parse the timeline ID from the output in
the python function that calls it.
The tenant ID was not actually generated here but in NeonEnvBuilder.
And the "neon_local init" command hasn't been able to generate the
initial tenant since 8712e1899e anyway.
## Problem
Having run in production for a while, we see that nodes are generally
safely oversubscribed by about a factor of 2.
## Summary of changes
Tweak the is_overloaded method to check for utililzation over 200%
rather than over 100%
## Problem
In https://github.com/neondatabase/neon/pull/8621, validation of keys
during ingest was removed because the places where we actually store
keys are now past the point where we have already converted them to
CompactKey (i128) representation.
## Summary of changes
Reinstate validation at an earlier stage in ingest. This doesn't cover
literally every place we write a key, but it covers most cases where
we're trusting postgres to give us a valid key (i.e. one that doesn't
try and use a custom spacenode).
The current code assumes that most of this functionality is
version-independent, which is only true up to v16 - PostgreSQL 17 has a
new field in CheckPoint that we need to keep track of.
This basically removes the file-level dependency on v14, and replaces it
with switches that load the correct version dependencies where required.
PR #7782 set the dependency in Cargo.toml to 'master', and locked the
version to commit that contained a specific fix, because we needed the
fix before it was included in a versioned release. The fix was later
included in parquet crate version 52.0.0, so we can now switch back to
using a released version. The latest release is 53.0.0, switch straight
to that.

## Summary of changes
This patch modifies the split delta layer writer to avoid taking
start_key and end_key when creating/finishing the layer writer. The
start_key for the delta layers will be the first key provided to the
layer writer, and the end_key would be the `last_key.next()`. This
simplifies the delta layer writer API.
On that, the layer key hack is removed. Image layers now use the full
key range, and delta layers use the first/last key provided by the user.

I wish it worked, but it's been broken for a long time, so let's admit
defeat and remove it.
The idea of sharing the same pageserver and safekeeper environment
between tests is still sound, and it could save a lot of time in our
CI. We should perhaps put some time into doing that, but we're better
off starting from scratch than trying to make TEST_SHARED_FIXTURES
work in its current form.
I wanted to use some features from the newer version. The PR that needed
the new version is not ready yet (and might never be), but seems nice to
stay up in any case.
We modified the crate in an incompatible way and upgraded to the new
version in PR #8076. However, it was reverted in #8654. The revert
reverted the Cargo.lock reference to it, but since Cargo.toml still
points to the (tip of the) 'neon' branch, every time you make any other
unrelated changes to Cargo.toml, it also tries to update the
rust-postgres crates to the tip of the 'neon' branch again, which
doesn't work.
To fix, lock the crates to the exact commit SHA that works.
