Enhance select accordion item

[asirvadAbrahamVarghese]

PR to include treeSelect API wait from selectAccordionItem command, which eliminates the need to handle this separately in every test.
This waits only when the request is actually triggered, since the treeSelect call may or may not fire if the node is already selected, as noted here

Based on what I’ve noticed the treeSelect POST API URL follows a common pattern across the app

• /report/tree_select?id=xx-0_xx-0-0_rep-20&text=Account%2520Groups%2520-%2520Linux
• /utilization/tree_select?id=mr-1&text=Region%25200
• /catalog/tree_select?id=-Unassigned&text=Unassigned
• /vm_or_template/tree_select?id=root&text=All%2520VMs%2520%2526amp%253B%2520Instances
• /vm_cloud/tree_select?id=xx-arch&text=%2526lt%253BArchived%2526gt%253B
• /vm_infra/tree_select?id=ms-107&text=Analysis%2520Failed
• /storage/tree_select?id=ms-30&text=Store%2520Type%2520%252F%2520FCP
• /pxe/tree_select?id=xx-xx-system&text=Examples%2520(read%2520only)
• /miq_ae_class/tree_select?id=aen-1322&text=zxc
• /ops/tree_select?id=z-2&text=%253Cstrong%253EZone%253A%2520Default%2520Zone%2520(current)%253C%252Fstrong%253E

which can be matched with /\/[^\/]+\/tree_select\?id=.*&text=.*/

LGTM. That URL pattern is pretty nasty due to inconsistency but at least it's only in 1 place now.
