We should allow running Sahara tests only when compute node has at least 4G RAM. That should greatly reduce number of such errors. Yaroslav, please implement the limit.

[Mike Scherbakov (mihgen)]

If this is Medium priority, please move it to 6.0 release to avoid limit risks of regression introduction with fixes another bugs like this one.

    Changes for Sahara and Murano OSTF tests

    We should allow running Sahara tests only when compute node has
    at least 4G RAM. That should greatly reduce number of errors. So this
    limit was added to OSTF tests for Sahara.

    Method for checking minimal free RAM of compute node was created and
    placed in class PlatformServicesBaseClass. Now OSTF tests for Murano
    use this method.

    Closes-Bug: #1334700
