We have these methods for some time in the API, so mentioning them in the
spec could be useful for console (see zenithdb/console#867), as we generate
pageserver HTTP API golang client there.
* Add --id argument to safekeeper setting its unique u64 id.
In preparation for storage node messaging. IDs are supposed to be monotonically
assigned by the console. In tests it is issued by ZenithEnv; at the zenith cli
level and fixtures, string name is completely replaced by integer id. Example
TOML configs are adjusted accordingly.
Sequential ids are chosen over Zid mainly because they are compact and easy to
type/remember.
* add node id to pageserver
This adds node id parameter to pageserver configuration. Also I use a
simple builder to construct pageserver config struct to avoid setting
node id to some temporary invalid value. Some of the changes in test
fixtures are needed to split init and start operations for envrionment.

Previous version of spec caused parsing errors in generated clients
as return type is object not array, also one field was missing. In
a passing set `format: hex` on ancestor_id too as value conforms to
that format.
This calculation is not that heavy but it is needed only in tests, and
in case the number of tenants/timelines is high the calculation can take
noticeable time.
Resolves https://github.com/zenithdb/zenith/issues/804
In order to exclude problems with synchronizing disk and memory logical
size is not stored in metadata on disk. It is calculated on timeline
"start" by scanning the contents of layered repo and then size is maintained
via an atomic variable.
This patch also adds new endpoint to pageserver http api: branch detail.
It allows retrieval of a particular branch info by its name. Size info
is also added to the response of the endpoint and used in tests.
