Remove testSuiteName and calculate test suite names automatically

[orchestr7]

1. We need to delete TestSuiteName
2. Calculate testSuite name based on the relative path from the root of test repo (root save.toml) to the directory
3. TestName should NOT contain full path and should be relative to it's test suite

Example:

[nulls]

We have excludedTest in save.toml and it expects a full path from root. can be changed to relative path\name after implementation of this issue

Another idea for cleanup of save.toml, as suggested by @sanyavertolet, is to filter distinct tags, because currently tags can be repeated.
