Reduce the number of file writes required by the credentials fallback. Disk write operations were done on every remote credentials read, now writes are only done if and only if there was a change in the target credentials list.
As part of this fix, it has been checked that if the network is fast enough 200 threads requesting credentials in parallel take lees than 2 seconds to conclude.
com.cloudbees.opscenter.client.plugin.OperationsCenterCredentialsProvider.cache.disabled was set to
true as a workaround for this issue, please make sure that property is removed after upgrading to this version.
