  Polish "Copy conversion service when performing environment conversion"
  Copy conversion service when performing environment conversion

Closes gh-9246

Previously, when a web environment was converted to a
StandardEnvironment, any customizations of the source environment's
ConversionService were lost.

This commit updates the logic that performs the conversion to copy
the source's ConversionService to the converted environment, thereby
ensuring that any customizations are retained.

Closes gh-9248

Prior to this commit, custom `ProtocolResolvers` set on the
`ApplicationContext` were lost when Devtools is used as the customized
`ResourceLoader` did not copy any customization made to the default
resource loader.

This commit makes sure to copy any `ProtocolResolver` set on the context.

  Ensure `QuartzDatabaseInitializer` is initialized before `Scheduler`

Closes gh-9411

If the auto-configured `Scheduler` instance backed by JDBC job store is
used as a dependency in an application component, the initialization of
`Scheduler` will be triggered before `QuartzDatabaseInitializer`. This
will result in failure due to schema not being prepared in time for
`Scheduler` to populate job details.

This commit ensures `QuartzDatabaseInitializer` is initialized before the
auto-configured `Scheduler` by introducing a dependency between the two.

  Document InfluxDB support

Closes gh-9404

See gh-9404

This commit removes the `client` namespace for InfluxDB as the
component that is created is `InfluxDB`, not `InfluxDBClient` or
something.

This aligns with all the other url/user/password properties Spring
Boot provides already
