> S3A: option "fs.s3a.performance.flags" to take list of performance flags

>                 Key: HADOOP-19161
>                 URL: https://issues.apache.org/jira/browse/HADOOP-19161
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: fs/s3
>    Affects Versions: 3.4.1
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>            Priority: Major
>              Labels: pull-request-available
>
> HADOOP-19072 shows we want to add more optimisations than that of 
> HADOOP-18930.
> * Extending the new optimisations to the existing option is brittle
> * Adding explicit options for each feature gets complext fast.
> Proposed
> * A new class S3APerformanceFlags keeps all the flags
> * it build this from a string[] of values, which can be extracted from 
> getConf(),
> * and it can also support a "*" option to mean "everything"
> * this class can also be handed off to hasPathCapability() and do the right 
> thing.
> Proposed optimisations
> * create file (we will hook up HADOOP-18930)
> * mkdir (HADOOP-19072)
> * delete (probe for parent path)
> * rename (probe for source path)
> We could think of more, with different names, later.
> The goal is make it possible to strip out every HTTP request we do for 
> safety/posix compliance, so applications have the option of turning off what 
> they don't need.
