Save test run ID and URL to be reused in CI

[NickVolynkin]

Test reporters create a Qase test run before reporting the tests. Subsequent CI steps might need the information about the run for many reasons:

• To report more tests to the same test run.
• To put the test run URL to the workflow description, PR comments, or wherever else.
• To query the API for some data from the test

Implementation

There can be several options to return the values:

Write variables to a file

qase.sh

QASE_TESTOPS_RUN_ID=42
QASE_TESTOPS_RUN_URL=https://app.qase.io/run/DEMO/dashboard/42

There can be a problem if such file already exists and is open for writing (that is, busy).
It can probably happen with multithreaded test runs.

Set environment variables

Same as with file, but directly set up env variables.
There's a risk of overwriting the value that was already set.
However, if it was set before running the tests, the reporter should have read and used it.

Write values to stdout in a well-parseable format
