Draft: Feat/sentry integration

Adds sentry tracking with some extra stuff to send more information than the bare minimum.

Most minimalistic integration would be doing:

sentry_sdk.init(dsn="https://0b5bdb7568e3e910af144dfb3c324dac@sentry.exfldadev01.desy.de/6")

There's more than that in this PR to add more context and data to what sentry sends:

• dist set from git status - includes info on the current commit hash and if repo is dirty or not
  • very much not required
  • might also not make sense when deployed
• functions_to_trace added programatically
  • to get more span info you can add @sentry_sdk.trace to functions/methods
  • alternative to this is providing a list of the fully qualified name of the thing you want to trace
  • doing this by making a list of some classes in calparrot, finding their methods, and adding those to be traced
• slurm job id tag - we can get env vars and explicitly set them as tags for better searching/visibility
  • could be expanded on
  • e.g. adding proposal number, run number, whatever, as tags
• setting span data for cache operations
  • by creating a span called cache.put/get and setting data with a few specific keys you tell sentry what this span is for
  • enables a special cache page view in the sentry interface
  • shows statistics like:
    • cache hit/misses
    • cache size
    • read/write times
  • just added this to play with, of all the things probably the most optional

Todo:

• set environment automatically
  • it's fixed to "testing" right now
  • should be "production" when running on xcal
  • I guess "testing" when on xcaltst
  • and maybe "development" otherwise (e.g. us running it)?
• set port correctly for cache data
  • if we keep the feature "network.peer.port" should be set to the actual port
  • lazily I hard coded it to 9000
• enable by default?
  • added a new --sentry flag to the CLI to enable integration
  • might make more sense to use environment to enable/disable conditionally?
    • production/testing always enabled unless --no-sentry passed
    • otherwise disabled unless --sentry passed
  • or presence of DSN as env var?
    • remove hard-coded DSN
    • enable if DSN env var present
    • disable otherwise
