General OMEROWrapper refactorization for passing directory

Reduce the number of locations that OMEROWrapper is created,
passing directory when it is clearly server-side.

Note: this currently does not compile because the OMEROWrapper
lives in blitz while everything else lives in romio.
Split OMEROWrapper to CachingWrapper for directory use

To simplify cleanup, having all caches written into a single
directory was added to the `loci.formats.Memoizer` class. Here,
hard-coded as `/tmp/memo`.

The various import related classes, howerver, are a tangle of
dependencies making it very difficult to not copy the same block of
code, e.g. the ReaderWrapper sequence and setting the proper
directory, throughout the code base.

By splitting OMEROWrapper into a CachingWrapper part in romio with
no dependencies on blitz we can mostly do this.

A few issues:
 * now, client-side caching is disabled
 * requires an insight dependency on romio
 * enforces use of a wrapper through ome.io.bioformats
 * allowed for preliminary, needed import class cleanup:
    - use of `wrap()` is encouraged
    - overriding `ReaderWrapper` method is discouraged
    - discourage holding on to wrapper instances

Merge remote-tracking branch 'origin/develop' into fs-file-caching

Two branches both tried to refactor the copy-n-paste
issues with reader creation. The combined solution means
it's possible to override createBfReader, but by default
a simple CachingWrapper will be returned.

A rebase would have been unduly arduous since in the early
commits of the fs-file-caching branch the CachingWrapper
which would be needed wasn't present, making bissecting
later impossible.

Minimal refactoring; limits where Memoizers are created

There is almost certainly more cleanup that can be done in terms of
where the reader stack is constructed and how it is stored.  This is at
least a start, and is hopefully safe and minimally invasive.

See #10750.

Memoizer refactoring
Add web proxy configuration support for linux clients network probes

Detect network availability in NetworkChecker using HTTP URL
instead of plain socket connection : this allows clients connecting
to the internet through a web proxy to configure HTTP proxy settings
for the JVM in startup shell scripts.
