Is your feature request related to a problem? Please describe.
Bring the structure of secrets with the configuration of various APIs to the same view and add an additional attribute that disables or enables these apis.

Describe the solution you'd like

• change the old secrets mega/dropbox -> uploader-api
• change the old secret instagram -> downloader-apii
• desired key scheme for uploader-api

  {
    "username": "username",
    "password": "password or token",          
    "storage-type": "mega or dropbox or local",
    "enabled": true or false (for disabled class),
    "exclude-types": "*.txt,*.tmp",
    "source-directory": "tmp/",
    "destination-directory": "mybot/"
  }

• desired key scheme for downloader-api

  {
    "username": "username",
    "password": "password or token",
    "login-method": "anonymous or password or session"
    "session-file": "path to session file",
    "enabled": true or false (for disabled class),
    "user-agent": "client user agent",
    "fatal-status-codes": [400, 401, 429, 500]
  }

• then delete all environment variables that depend on the new structure
  - TEMPORARY_DIR
  - STORAGE_TYPE
  - STORAGE_EXCLUDE_TYPE
  - INSTAGRAM_SESSION
  - INSTAGRAM_USERAGENT
