Action that handles the tag creation part of the feature.

[vhudlikar]

I have created an Action that handles the tag creation part of the feature. #7 (comment)

Logic:

1. Check if a tag with the provided Tag Name already exists in the Tags [label] table.
2. If it does not exist, create a new tag record with that name.
3. Return the Sys ID of the newly created tag.
4. If the tag already exists, it should likely not create a duplicate but instead return the Sys ID of the existing tag by setting tag as active.

Testing Done for Action:

1. Input provided to action with Name as "Hacktoberfest".
   -> Result: New Tag was created with same Name with Active as true.
2. Input provided to action with same name again as "Hacktoberfest".
   -> Result: Instead of new tag creation it provided sys_id of existing record.
3. Existing record which was created in Test Step 1, mark it as inactive and Input provided to action with same name again as "Hacktoberfest".
   -> Result: Script was able to detect existing tag which was made active and sys_id was return which match with sys_id for the record created in Test Step 1.
