[Misieq01]

#891 #905 #892

[ Content ]

• Added caching for each of versions list that we download for binaries
• Added caching of metadata needed to handle caching versions list ( githubEtag, mirrorEtag, file_path ))
• Added mechanism to decide if we should use cached versions list or download them based on comparing eTags and checking if files exists
• Improved mirror downloading by sending head request fist and checking cf-cache-status header if returns `HIT

[ Testing ]

• Remove binaries and cache from tari cache dir:
  /// - **Linux:** Resolves to $XDG_CACHE_HOMEor$HOME/.cache.
/// - **macOS:** Resolves to $HOME/Library/Caches.
/// - **Windows:** Resolves to {FOLDERID_LocalAppData}.
• set should_check_for_update in main.rs to true ( it will help with testing )as it force app to check for new binaries versions online, by default it happens once per 6 hours
• After app setup is done you should see binaries and cache present and cache/binaries_versions should include jsons with version releases list
• Logs should include entries from RequestClient.check_if_cache_hits about checking cf-cache-status values and there should also be logs from CacheJsonFile about cache mechanism working
