Upgrade to 1.0 SPI

[elefeint]

R2DBC 1.0 went GA last month.

For 0.9:
The biggest changes are a new parameter binding facility for specifying data types, and the extended transaction definition (useful for Spanner's readonly / stale transactions)

Note: the current codebase is on 0.9 SPI already, although the released version is only on 0.8.

Any plans for a new release using at least 0.9 SPI? There was a breaking change fetching column metadata: r2dbc/r2dbc-spi#219

java.lang.AbstractMethodError: Receiver class com.google.cloud.spanner.r2dbc.v2.SpannerClientLibraryRowMetadata does not define or inherit an implementation of the resolved method 'abstract java.util.List getColumnMetadatas()' of interface io.r2dbc.spi.RowMetadata.

Without 0.9 fetching the metadata fails.
Edit: Nevermind, 1.2.0 already uses 0.9.
