Huaisi Xu c1da1409ba IMPALA-3711: Remove unnecessary privilege checks in getDbsMetadata() ...

Previously all code paths using getDbsMetadata() sufferred
unnecessary privilege checks:
1. Impala checked privilege of all databases, tables before
applying user provided JDBC pattern filters.
2. Impala passed a null pattern to getDbsMetadata() when
user did not provide one. However, null pattern is treated
as "%", which matches everything thereby causing unnecessary
privilege checks for catalog objects that are not in the
result set.

This patch creates PatternMatcher early so that user specified
null pattern is respected when calling getDbsMetadata().
