Terrascan creates ~/.terrascan even though policy directory is supplied

• terrascan version: 1.31.1
• Operating System: All

Description

Terrascan creates ~/.terrascan directory even when you have specified a policy directory for scanning purposes. It would be preferable if Terrascan could be run without always creating this directory.

What I Did

Attempted to prevent the creation of ~/.terrascan by performing the following:

1. Initiate a local scan on some code in a local directory to get Terrascan to download policies.
2. Copy /pkg/policies to a local directory ~/ts/policies/
3. Delete ~/.terrascan
4. Re-run Terrascan using -p ~/ts/policies

Expected result:
Terrascan would use the policies in the specific directory and not need to download the repository into ~/.terrascan

Actual result:
Terrascan recreated the ~/.terrascan directory even though it used the policies in the directory that was specified.
