change pg_hba.conf to be owned by postgres user account

At present, the ownership of pg_hba.conf is hardwired to be uid 0.  It should have the same ownership as all of the other postgressql configuration files in the same cluster so that they can be managed/edited by the postgres role user (system) account.

Adds "Release Notes/Known Bugs" to Changelog, updates file format to markdown, standardizes the format of previous entries

Per a request to have initial release notes that specifically listed known issues for this PE 3.2 release, and barred by time constraints from automating a pull from open issues in JIRA, this commit adds a Release Note and Known Bug section to the Changelog for the imminent 3.2 release. As it will display on the Forge, updates file type to markdown and standardizes previous entries. Adds template for release notes to be filled in later.
