@SpringResource block Service Node bootstrap when the node starts at the first time

@SpringResource block Service Node bootstrap and service deployment when the node starts at the first time. After killing the service node and restarting, the service is deployed successfully.

My steps is

1. Start the data node

```
fun main(args: Array<String>) {
SpringApplication(DataNodeApplication::class.java).apply {
addInitializers(
ApplicationContextInitializer<GenericApplicationContext>

{ DataNodeApplication.beans().initialize(it) }

)
}.run(*args)
}

@SpringBootConfiguration
@EnableAutoConfiguration
class DataNodeApplication {

companion object {
fun beans() = beans {
bean("igniteInstance") {
// Ignite configuration with all defaults
// and enabled p2p deployment and enabled events.
val igniteConfig = IgniteConfiguration().apply {
isPeerClassLoadingEnabled = true

/*
Labeling Data Nodes with special attribute.
This attribute is checked by common.filters.DataNodeFilters
which decides where caches have to be deployed.
*/
userAttributes = mutableMapOf("data.node" to true)

// Configuring caches that will be deployed on Data Nodes
setCacheConfiguration(
// Cache for QuoteRequest
CacheConfiguration<Int, QuoteRequest>().apply

{ name = "QuoteRequest" /* Enabling a special nodes filter for the cache. The filter will make sure that the cache will be deployed only on Data Nodes, the nodes that have 'data.node' attribute in the local node map. */ nodeFilter = DataNodeFilter() }

,
// Cache for Maintenance records
CacheConfiguration<Int, Maintenance>().apply {
name = "maintenance"
/*
Enabling a special nodes filter for the cache. The filter
will make sure that the cache will be deployed only on Data
Nodes, the nodes that have 'data.node' attribute in the local
node map.
*/
nodeFilter = DataNodeFilter()

// Enabling our sample cache store for the Maintenance cache
setCacheStoreFactory(FactoryBuilder.factoryOf("common.cachestore.SimpleCacheStore"))

// Avoid Maintenance objects deserialization on data nodes side
// when they are passed to SampleCacheStore.
isStoreKeepBinary = true

// Enabling the write-through feature for the store.
isWriteThrough = true

// Enabling the read-through feature for the store.
isReadThrough = true

// Configuring SQL schema.
queryEntities = listOf(
QueryEntity().apply

{ // Setting indexed type's key class keyType = "java.lang.Integer" // Setting indexed type's value class valueType = "entity.Maintenance" // Defining fields that will be either indexed or queryable. // Indexed fields are added to 'indexes' list below. fields = linkedMapOf("vehicleId" to "java.lang.Integer") // Defining indexed fields. // Single field (aka. column) index indexes = listOf(QueryIndex("vehicleId")) }

)
}
)

discoverySpi = discoverySpi()
}

IgniteSpringBean().apply

{ configuration = igniteConfig }
}
}
}
}
```

2. Start the service node

```
fun main(args: Array<String>) {
SpringApplication(RequestForQuoteServiceNode::class.java).apply {
addInitializers(
ApplicationContextInitializer<GenericApplicationContext> { RequestForQuoteServiceNode.beans().initialize(it) }
)
}.run(*args)
}

@SpringBootConfiguration
@EnableAutoConfiguration
@EnableIgniteRepositories("repository")
class RequestForQuoteServiceNode {

companion object {
fun beans() = beans {
bean("igniteInstance") {
// Ignite configuration with all defaults
// and enabled p2p deployment and enabled events.
val igniteConfig = IgniteConfiguration().apply {
isPeerClassLoadingEnabled = true

/*
Labeling QuoteRequest Service nodes with special attribute.
This attribute is checked by common.filters.VehicleServiceFilter.
Due to the filter, the RequestForQuoteService might be deployed only on
the nodes with this special attribute set.
*/
userAttributes = mutableMapOf("vehicle.service.node" to true)

setServiceConfiguration(
// Setting up RequestForQuoteService.
// The service will be deployed automatically
// according to the configuration below.
ServiceConfiguration().apply { name = "RequestForQuoteService" // Don't initialize service's properties here. Ignite's deployment // will discard them. service = RequestForQuoteServiceImpl() // Only one instance of the service will be deployed cluster wide totalCount = 1 // Only one instance of the service can be deployed on a single node. maxPerNodeCount = 1 /* Enabling a special nodes filter for this service. The filter will make sure that the service will be deployed only on the nodes that have 'quoteRequest.service.node' attribute in the local node map. */ nodeFilter = VehicleServiceFilter() }
)

discoverySpi = discoverySpi()
}

IgniteSpringBean().apply { configuration = igniteConfig }

}
}
}

}
```
