Standardize support for Names vs Numbers for Levels

[martindsouza]

Some of the code takes in numbers and other parts take in names for level references. Overload all code like this so one standard is across the board and have a common option for all code on a go forward basis so it's consistent.

It turns out that when overloading set_level will cause some issues.

procedure set_level(
  p_level in varchar2 default logger.g_debug_name,
  p_client_id in varchar2 default null,
  p_include_call_stack in varchar2 default null,
  p_client_id_expire_hours in number default null
);

procedure set_level(
  p_level in number,
  p_client_id in varchar2 default null,
  p_include_call_stack in varchar2 default null,
  p_client_id_expire_hours in number default null
);

Then calling:

begin
  logger.set_level(
    p_level => 2,
    p_client_id => 2
  );
end;
/

ORA-06550: line 2, column 3:
PLS-00307: too many declarations of 'SET_LEVEL' match this call

To get around this issue will only have one instead of set_level and check to see if p_level is a number.
