Adding support for ACL, Content-Type, Max File Size and allowed Content-Types

[seriousben]

Adds support for:

• ACL
• Content-Type
• Max File Size (defaults to 10 MB)
• Allowed Content-Types

Notes:

• Max File Size will not cause the whole file to be downloaded, but will not cleanup after itself for now. We should discuss the best way to do this.

Examples:

var dsImage = loopback.createDataSource({
  connector: require('loopback-component-storage'),
  provider: 'filesystem',
  root: path.join(__dirname, 'images'),

  getFilename: function(fileInfo) {
    return 'image-' + fileInfo.name;
  },
  acl: 'public-read',
  allowedContentTypes: ['image/png', 'image/jpeg'],
  maxFileSize: 5 * 1024 * 1024
});

or using the handler directly:

handler.upload(req, res, {
  container: 'images',
  maxFileSize: 10 * 1024 * 1024,
  allowedContentTypes: ['image/png', 'image/jpeg'],
  acl: 'public-read',
  getFilename: function(fileInfo) {
    return 'image-' + fileInfo.name;
  }
}, function(err, result) {
});
