The base FileSystem implementation generally has no knowledge
of the capabilities of actual implementations.
Unless it has a way to explicitly determine the capabilities,
this method returns false.
Probe for a specific capability under the given path.
If the function returns <code>true</code>, this instance is explicitly
declaring that the capability is available.
If the function returns <code>false</code>, it can mean one of:
<ul>
<li>The capability is not known.</li>
<li>The capability is known but it is not supported.</li>
<li>The capability is known but the filesystem does not know if it
is supported under the supplied path.</li>
</ul>
The core guarantee which a caller can rely on is: if the predicate
returns true, then the specific operation/behavior can be expected to be
supported. However a specific call may be rejected for permission reasons,
the actual file/directory not being present, or some other failure during
the attempted execution of the operation.
