Summary:
Priliminary diff to solicit comments.
Given DB path, dump all SST files (key/value and properties), WAL file and manifest
files. What command options do we need to support for this command? Maybe
output_hex for keys?
Test Plan: Create additional ldb unit tests.

Summary:
If the last byte of the timestamp is 0, the output value of the ttl db
can cut off earlier. Change to compare hex format instead.
Test Plan:
this does not happen consistently, but it did not fail after the last
100 runs
for i in {1..100}; do python ./tools/ldb_test.py; done

Summary: Added an option --count_delim=<char> which takes the given character as delimiter ('.' by default) and reports count of each row type found in the db
Test Plan:
1. Created test in file (for DBDumperCommand) rocksdb/tools/ldb_test.py which puts various key value pair in db and checks the output using dump --count_delim ,--count_delim="." and --count_delim=",".
2. Created test in file (for InternalDumperCommand) rocksdb/tools/ldb_test.py which puts various key value pair in db and checks the output using dump --count_delim ,--count_delim="." and --count_delim=",".
3. Manually created a database with several keys of several type and verified by running the command
./ldb db=<path> dump --count_delim="<char>"
./ldb db=<path> idump --count_delim="<char>"

Summary: ldb works with raw data from the database and needs to be aware of ttl-database to work with it meaningfully. '-ttl' option now tells it that. Also added onto the ldb_test.py test. This option may be specified alongwith put, get, scan or dump. There is no support to provide a ttl-value and it uses default forever because there is no use-case for this currently.
Test Plan: make ldb_test; python tools/ldb_test.py

Summary: ldb_test.py did a lot of assertFalse checks and displayed all the failed messages on the std output making it confusing to tell a successful from a failed run. Also many empty lines used to be needlessly printed. Also added some progression-"feel-good" lines in the tests
Test Plan: python ldb_test.py
