[server][SQLUtils] Add a new method: getFullName().
[server][ArmNagiosNDOUtils] Fix a wrong parameter of the column definition.

This is a potential problem and doesn't cause any problem in present,
because they are not used.
(We'll use them in the development of this branch).
[server] Don't use table name variables.

Instead, this patch uses the table name itself when it's needed.
The interfaces of some method taking a table name variable still
exists. In the next step, I will remove them and the definitions.
[server][DBAgent] Remove the unused paramter due to the previous commit.
[server] Remove interfaces and definitions for using table name variables.

As a result, we could make code simple.
