**Please** add a meaningful description for your change here
When outputting to lots of files (one file per PCollection element), Beam
creates many GcsPath objects. Each object validates the bucket name that it
will be writing to, which tends to create a lot of memory allocation. When
this allocation occurs, the GC kicks in and spends a lot of time moving memory
around, which results in The MemoryMonitor kicking in and killing the process.
In my experience, typically the MemoryMonitor kills the instance even when
ample memory is available, primarily because the GC more active than normal.
This change attempts to allocate less garbage by caching the Regex, and thus
avoid the overactive GC.
I started off by noticing my jobs typically dying in the final stage of
Writing the output files, typically due to MM. Profiling the jobs directly
with Async Profiler revealed the source of the allocation coming from GcsPath,
using the uncached String regex. A sample of the error, and the Async Profiler
output has been included for posterity.
Cloud Dataflow log line:
```
Shutting down JVM after 8 consecutive periods of measured GC thrashing.
Memory is used/total/max = 4687/21835/40027 MB, GC last/max = 89.73/99.10 %,
#pushbacks=0, gc thrashing=true. Heap dump written to
'/var/log/dataflow/heap_dump.hprof'.
```
(note the ample memory available, and lack of memory pressure).
Allocation top sample:

(alas, I don't personally know anyone on the Beam team, nor have access to
the JIRA, so I will be unable to fill most of the next section). While this is
my first GitHub issue, I have been using Beam since it was FlumeJava back in
2014.)
