* 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
This removes big shared lock held for for the duration of each request
and replaces it with trivially short lock to capture the current
state of the server/repository before passing it to handlers.
Handlers are now limited to only accessing a small subset of Server
functionality to be able to better reason about them.
* cli: added --tls-print-server-cert flag
This prints complete server certificate that is base64 and PEM-encoded.
It is needed for Electron to securely connect to the server outside of
the browser, since there's no way to trust certificate by fingerprint.
* server: added repo/exists API
* server: added ClientOptions to create and connect API
* server: exposed current-user API
* server: API to change description of a repository
* htmlui: refactored connect/create flow
This cleaned up the code a lot and made UX more obvious.
* kopia-ui: simplified repository management UX
Removed repository configuration window which was confusing due to
the notion of 'server'.
Now KopiaUI will automatically launch 'kopia server --ui' for each
config found in the kopia config directory and shut it down every
time repository is disconnected.
