[curve tool]: implement seginfo command

[cw123]

Describe the feature you'd like:

we'd like to support seginfo command in curve tool

seginfo is one of the commands to list the segments info of the volume.

• The implementation of the old tool is here：

https://github.com/opencurve/curve/blob/master/src/tools/namespace_tool.cpp#L277

• The old command input and out put:

seginfo : list the segments info of the file

$ curve_ops_tool seginfo list --example
Example:
curve_ops_tool seginfo -mdsAddr=127.0.0.1:6666 -fileName=/test

$ curve_ops_tool seginfo -fileName=/test
logicalPoolID: 3
startOffset: 0
segmentSize: 1073741824
chunkSize: 16777216
chunks:
chunkID: 21227073, copysetID: 969
chunkID: 21227074, copysetID: 970
chunkID: 21227075, copysetID: 971
chunkID: 21227076, copysetID: 972
chunkID: 21227077, copysetID: 973
chunkID: 21227078, copysetID: 974
.......

logicalPoolID: 2
startOffset: 1073741824
segmentSize: 1073741824
chunkSize: 16777216
chunks:
chunkID: 21227201, copysetID: 5518
chunkID: 21227202, copysetID: 5519
chunkID: 21227203, copysetID: 5520
chunkID: 21227204, copysetID: 5521
chunkID: 21227205, copysetID: 5522
.......

• The new command we want:

curve bs seginfo /curvebs-file-name

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

The old output format is inconvenient to read. Need to improve the presentation of results in new tools
