Support ORDER BY/WHERE for all show commands

[murphyatwork]

Enhancement

show command can support several clauses:

• ORDER BY: sort by particular field
• WHERE: use a predicate to filter data
• FROM : from a table
• LIKE: filter by table name

But the implementation is not consistent, some of show commands can support most of them, like show tablets. But most of other commands do not really support these clauses.

So the idea is to make all show command support all these clauses, to make it more user-friendlly.
