[curve tool]: implement create volume command

[cw123]

Describe the feature you'd like:

we'd like to support create command in curve tool

create is one of the commands to create one volume.

• The implementation of the old tool is here：

https://github.com/opencurve/curve/blob/master/src/tools/namespace_tool_core.cpp#L63

• The old command input and out put:

create : create file, file length unit is GB

$ curve_ops_tool create --example
Example:
curve_ops_tool create -mdsAddr=127.0.0.1:6666 -fileName=/test -userName=test -password=123 -fileLength=20‬

• The new command we want:

curve bs create --filename /curvebs-file-name --username username --filelength the_length_num_of_volume [--password password] 

If command sucess, print success.
If command failed, print failed, and the fail reason.

Teachability, Documentation, Adoption, Migration Strategy:

Refer to tool develop guide to get start, and paste the result of the command in pr.

Build compilation environment：https://github.com/opencurve/curve/blob/master/docs/cn/build_and_run.md

@Cyber-SiKu Can you take a look at this？

[Cyber-SiKu]

Please submit your code and let me have a look.

[wuhongsong]

@wangyanghack keep on? Can you tell more about your troubles?

@wangyanghack keep on? Can you tell more about your troubles?

I have submitted my code. But I don't know how to get more details from log.

curve/tools-v2/pkg/cli/command/curvebs/create/create.go

Lines 107 to 113 in 3e6357b

	createCommand.Response = result.(*nameserver2.CreateFileResponse)
	if createCommand.Response.GetStatusCode() != nameserver2.StatusCode_kOK {
	err = cmderror.ErrBsCreateFile()
	out[cobrautil.ROW_RESULT] = "failed"
	out[cobrautil.ROW_REASON] = err.Message
	return nil
	}

Here you create the error, and you can see that the reason for the error is: the returned status code is not ok. You can call err.Formate() to fill in the following %s.

[wangyanghack]

thanks a lot! I will try it tonight.

[wangyanghack]

The returned status code is kFileLengthNotSupported. But it is strange. I search all code. I find kFileLengthNotSupported is not related with curvebs.

[Cyber-SiKu]

@wangyanghack Please update the code

[Cyber-SiKu]

@wangyanghack Are you still going on?

[Cyber-SiKu]

@wangyanghack If you have any questions, you can contact us in time.
