Optimize ListActiveLedgersCommand

[AnonHxy]

Motivation

1. Optimze bookkeepr shell activeledgers .
   Currently activeledgers only print the ledger id of the active ledgers. if we want to know the size of the active ledgers in then entry log, we need caculate manually.

In this PR, we will also print the active ledgers and the usage of the entrylog.

2. No more print usage of the entrylog in bookkeepr shell readlogmetadata, because the usage will always be 1.0 which is a false result.

3. Examples after optimization

• bin/bookkeeper shell activeledgers

before:

after:

• bin/bookkeeper shell readlogmetadata

before:

after:

Changes

1. Print more info in activeledgers cmd
2. No more print usage in readlogmetadata cmd
