Unable to convert database to latin1 instead of utf8 if desired

[TheWitness]

Describe the bug

There is presently no way to mass convert tables to latin1 if you are space constrained and don't use international characters.

To Reproduce

Steps to reproduce the behavior:

1. Go to cli folder

2. Run ./convert_tables.php --help

3. There is no latin1 option

Expected behavior

Cacti should provide the ability to move between utf8mb4 and latin1

[netniV]

It should be noted, this will make the installer request table conversion each time until utf8 is restored.

[TheWitness]

Yea, maybe we should have set the character set for the whole tables and verify against that.

[netniV]

No I believe the default of UTF8's is correct for modern dbs

[TheWitness]

We will have to address as a feature in 1.3.
