ISPN-4153 Server can't start a cache with custom cache store

* Added a nonStrict method so we can use the default BaseConfigurationBuilder

ISPN-3514 Align XML configuration between Server and Embedded

* The objective is for server configuration to be readable by embedded
and viceversa.
* Those elements that are not relevant for embedded configuration are
ignored and highlighted with an INFO message.
* All configuration affecting test results has been adjusted.
* This commit does not include changes to demos, documentation or
schema files. This will come later, once the XML has been fully agreed.
* If there's any testing XML that has not been converted, it's because
it's not being tested at all, it should be removed in the cleanup phase.
* During the cleanup phase, all unused attributes/elements and parsers
will be removed.
* The XML in general follows the pattern used by server which means
that there are some noticeable changes to the way embedded XML is
configured:
* Cache mode is now part of the cache definition, i.e. local-cache,
distributed-cache...etc.
* Default cache is now specified at the cache container level, naming
it.
* Shutdown hook now configured as an attribute of cache instead of
a separate element.
* X-Site local site derived from transport's site-id, instead of adding
yet another xml configuration option.
* Compatibility mode drops enabled attribute, element being present
enables it.
* Same thing happens with versioning, element being present enables it.
* Deadlock detection's spin duration used to enable/disable it. If
configured with a value below 0, it's disabled.
* unsafe.unreliableReturnValues is now configured via an attribute
instead of a separate element.
* store-as-binary is disabled by making sure keys and values are both
set to false.
* L1 is disabled by making its lifespan -1.
* Replication queue configured via cache level attributes, and it's
disabled by making the queue size negative.
* Simplified thread pool configuration by avoiding to leak XML
configuration details into programmatic API. In the programmatic
version, just provide factories.
* Fixed thread pool injection in server.
