[Feature] add upload data parts in parallel for increase upload speed.

[happygupta]

i want to know can you please add multipart upload simultaneously. when user upload data its speed very low. this feature will help for increasing speed of uploading data. you can take one more option (eg: maxParallelupload : default value is 1 and it will increase with up to 8). i take a reference form this repo i mention below. we can use like that. and also we take support ISOLATE for that if it's necessary.
