def _check_existence(self, name):
"""
For regexp names:
If only part of packages were installed during early canceling.
Let's say:
1. install hbase_2_3_*
2. Only hbase_2_3_1234 is installed, but is not hbase_2_3_1234_regionserver yet.
3. We cancel the yum
In that case this is bug of packages we require.
And hbase_2_3_*_regionserver should be added to metainfo.xml.
Checking existence should never fail in such a case for hbase_2_3_*, otherwise it
gonna break things like removing packages and some others.
Note: this method SHOULD NOT use yum directly (yum.rpmdb doesn't use it). Because a lot of issues we have, when customer have
yum in inconsistant state (locked, used, having invalid repo). Once packages are installed
we should not rely on that.
