Bug While Creating a New Tag From Backend

[zanpizmoht]

Describe the bug
When creating a tag manually through back end and SQL case there is no checking if the tag name is too short, too long, or contains invalid symbols.

To Reproduce
Steps to reproduce the behaviour:

1. In the code, manually create a tag with name "A" with create method from TagServiceImpl.java
2. The tag is created, but it should not be as it is too short (the same goes for too long names and names with invalid symbols)

OR

1. Start KAPUADB
2. Type in the SQL case such as: INSERT INTO KAPUADB.TAG_TAG (SCOPE_ID, ID, CREATED_BY, MODIFIED_BY, NAME) VALUES (1, 6883354369915964061, 1, 1, ‘A’)
3. Tag with too short name should not be created but this is not the case

Expected behavior
The backend should return exception KapuaException.
