Documentation issue with required parameters 'size_file' or 'time_file'

[gmoskovicz]

Docs report that time_file and size_file are optional, but you need to at least set one of those to make this work:

output {
   s3{
     access_key_id => "crazy_key"             (required)
     secret_access_key => "monkey_access_key" (required)
     endpoint_region => "eu-west-1"           (required)
     bucket => "boss_please_open_your_bucket" (required)
     size_file => 2048                        (optional)
     time_file => 5                           (optional)
     format => "plain"                        (optional)
     canned_acl => "private"                  (optional. Options are "private", "public_read", "public_read_write", "authenticated_read". Defaults to "private" )
   }

I suggest we do this:

• Set a default value to size_file to 1024
• Set a default value to time_file to 10 minutes
• Add a validation to make sure both of theses values arent 0.

Also update this part of the doc:

beware if you specific 0 and size_file 0, because you will not put the file on bucket, 
for now the only thing this plugin can do is to put the file when logstash restart.

Also clarify the docs to explain what the file will look like on the bucket. Chunks/part etc.

Following the comment from @gmoskovicz

looks like this will upload the entire file, but it actually creates chunks of the file and it sends it periodically (depending on the size or the refresh rate)

SGTM! @ph :+1:

@ph This can be closed, correct? The code now specifies defaults as you suggested, and a proper exception is raised if both size_file and time_file are set to 0.
