> Add libhdfs APIs for openFile

> HADOOP-15229 added a "FileSystem builder-based openFile() API" that allows
> specifying configuration values for opening files (similar to HADOOP-14365).
> Support for {{openFile}} will be a little tricky as it is asynchronous and
> {{FutureDataInputStreamBuilder#build}} returns a {{CompletableFuture}}.
> At a high level, the API for {{openFile}} could look something like this:
> {code:java}
> hdfsFile hdfsOpenFile(hdfsFS fs, const char* path, int flags,
> int bufferSize, short replication, tSize blocksize);
> hdfsOpenFileBuilder *hdfsOpenFileBuilderAlloc(hdfsFS fs,
> const char *path);
> hdfsOpenFileBuilder *hdfsOpenFileBuilderMust(hdfsOpenFileBuilder *builder,
> const char *key, const char *value);
> hdfsOpenFileBuilder *hdfsOpenFileBuilderOpt(hdfsOpenFileBuilder *builder,
> const char *key, const char *value);
> hdfsOpenFileFuture *hdfsOpenFileBuilderBuild(hdfsOpenFileBuilder *builder);
> void hdfsOpenFileBuilderFree(hdfsOpenFileBuilder *builder);
> hdfsFile hdfsOpenFileFutureGet(hdfsOpenFileFuture *future);
> hdfsFile hdfsOpenFileFutureGetWithTimeout(hdfsOpenFileFuture *future,
> int64_t timeout, javaConcurrentTimeUnit timeUnit);
> int hdfsOpenFileFutureCancel(hdfsOpenFileFuture *future,
> int mayInterruptIfRunning);
> void hdfsOpenFileFutureFree(hdfsOpenFileFuture *future);
> {code}
> Instead of exposing all the functionality of {{CompleteableFuture}} libhdfs
> would just expose the functionality of {{Future}}.
