Will give hint when any job failed to assign:
```
Please add the following jobs to .gitlab-ci.yml with specific tags:
* Add job with: psram, ESP32_IDF, UT_T1_1
* Add job with: psram, ESP32_IDF, UT_T1_1
```
We have built unit-test-app with different configs.
Currently we use the config name as tags to match runners.
It's not easy to add new configs (need to update tags to existed runners).
Now we'll parse required test runner tags from `sdkconfig` file.
For example, if config enables `CONFIG_SPIRAM_SUPPORT`, then it requires `psram` tag.
This will make adding new configs easier.
In this commit we change the one behavior of assign test: match keys of
cases should be exactly the same with job tags. This fixes cases select
jobs include their tags, and jobs requires those tags can't be assigned.
1. configs are not functional
* decorator will be executed when search case, need to set default config before search case.
2. fix DUT encode/decode errors
* python3 serial don't support write string/unicode, need to convert to bytes first.
* python2 string could failed to encode/decode non-acsii chars
3. fix bug that log folder not created
4. fix bug that test suite name is not correctly passed:
* the keyward arg should be `test_suite_name` not `test_name`
5. fix bug that test stopped on failed case
6. fix DUT `read` don't return all data cache
* `_DataCache.get_data` should first copy all data from queue to data cache and then return to user.
7. fix bug that `expect_all` failed even all expected item passed
8. optimize error info for expect
* print pattern for regular expression when match failed
9. fix bug that set default config doesn't work
1. Attenuator: control programmable attenuator
2. PowerControl: control APC PDU to power on/off devices
3. LineChart: use matplotlib to draw line chart
