db: support store-relative paths for WAL dirs
Relative WAL paths (including the actual WAL, the failover path, and
the recovery paths) are (unfortunately) interpreted as relative to the
current working directory.
The cross-version metamorphic test copies a store from a previous run
as the initial state for a new test. The options will fail the
compatibility check since the path changes.
This change adds support for using a special
{store_path}
prefix tothe path. Any such prefix is replaced with the store directory.
We also improve the missing WAL recovery dir error to show what
directories are actually configured.
metamorphic: use store-relative paths
metamorphic: fix code around WAL recovery directories
