[tools] Add 'kudu local_replica edit_metadata delete_rowsets' to delete rowsets from tablet

There are some use cases we need to delete rowsets from a tablet.
For example：
1. Some blocks are corruption in a single point cluster, the server cannot be
   started. Note: some data will be lost in this case.
2. Some rowsets are fully deleted but the blocks can not be GCed (KUDU-3376).
   Note: no data will be lost in this case.

Although we can use 'kudu pbc edit' to achieve this aim, but it's very hard to
operate when the tablet-metadata is dozens of megabytes.

This patch introduce a CLI tool 'kudu local_replica edit_metadata delete_rowsets'
to delete rowsets from a tablet, which is easier to use.
