dynamically list test files

[dev-jonghoonpark]

Related issue
#13219

Motivation
Currently we have to manually update the all_tests variable when introducing new test files.

Modification
I have modified it to list test files dynamically, but instead of modifying it to add all test files, I have modified it to only add only test files from the following 4 paths

• unit
• unit/type
• unit/cluster
• integration

so that it doesn't deviate too much from what we already do

Result

• dynamically list test files to all_tests variable
• close issue [NEW] dynamically list test files #13219

Additional information

• removed list-common.tcl file and added generate_largevalue_test_array proc in util.tcl. because list-common.tcl is not a test file
• There is an order dependency. So I added a code to the "Is a ziplist encoded Hash promoted on big payload?" test that resets hash-max-listpack-value to the default (64).
