* chore(ci): upgraded linter to 1.53.3
This flagged a bunch of unused parameters, so the PR is larger than
usual, but 99% mechanical.
* separate lint CI task
* run Lint in separate CI
* implemented format blob cache abstraction
* moved upgrade lock logic to repo/format
* moved set parameters logic to repo/format
* moved change password functionality to repo/format
* mechanical changes
* mechanical changes to react to format manager interface
* get current repository format bytes instead of static
* implemented format.Manager which dynamically fetches and caches latest format blob
* repo changes to use format.Manager
* fixed failing unit test due to different timings
* reduced lock contention by using RWMutex
* serve immutable parts of format without any locks
* increase test timeout
* fixed handling of negative validDuration
The new rules are:
- validDuration < 0 - ignore initial cached file, refresh every 15min
- validDuration > 15min - refresh every 15 minutes
- validDuration > 0 && validDuration <= 15min - refresh using provided
interval (mostly used for testing)
* refactor(repository): moved format blob management to separate package
This is completely mechanical, no behavior changes, only:
- moved types and functions to a new package
- adjusted visibility where needed
- added missing godoc
- renamed some identifiers to align with current usage
- mechanically converted some top-level functions into member functions
- fixed some mis-named variables
* refactor(repository): moved content.FormatingOptions to format.ContentFormat
