Expose audit message grid search from ServiceInsight in ServicePulse

[PhilBastian]

Describe the feature.

Note: this issue has #2130 as a prerequisite, which will create the audit grid

This issue is for exposing the audit message search functionality in ServicePulse, currently only accessible in ServiceInsight.

Requirements

• Supply a textbox that the user can provide a search term in
• Retrieve messages from ServiceControl http://servicecontrolurl/api/messages/search according to the supplied search term
• Display messages details in the audit grid
• If the current page selected on the audit grid would be higher than the number of pages after search then this should be handled gracefully

The search should only occur on explicit user request (e.g. button press), as otherwise this would likely cause performance issues.

Note: A few issues relating to the search functionality in ServiceInsight have been raised. Consider reading through these to see if any could be addressed as part of this effort:

• Message search does not work with pagination ServiceInsight#1360
• SearchTerms with colon (:) in it will yield invalid too many (invalid) results ServiceControl#3468 <-- may no longer be an issue?
• Add the ability to search using the 'AND' clause between the search terms ServiceInsight#1401
• Ability to search based on header value exact and wildcard matching ServiceInsight#1059
• https://github.com/Particular/ServiceInsight/issues?q=is%3Aissue+is%3Aopen+search
