OSTF Murano tests should delete environment 'ost1_test-Murano_env01' in tearDown method

[Timur Nurlygayanov]

Steps To Reproduce:
1. Run Sanity Murano OSTF tests on host with low performance.
2. Check the list of Murano environments

Observed Result:
Sanity tests fails with timeout, Environment still in the list of environments.

In logs we can see the following error (and it is the root of problem):
muranoclient.common.http: DEBUG: curl -i -X POST -H 'X-Auth-Token: 85737f10a0e846fcbde0c8b7853787d7' -H 'Content-Type: application/json' -H 'User-Agent: python-muranoclient' -d '{"name": "ost1_test-Murano_env01"}' http://10.20.0.12:8082/environments

    Fixed issue with tearDown method for Murano tests

    with specific prefix and remove them all after tests.
